I think many of the above listed characteristics are quite individual, so it is very difficult to generalise about those features on a wide scale based on nationality, equally many of those characteristics apply to non-Slavic people(s) as much as they apply to Slavic people.
To be honest, I think on the surface, Russians and Poles probably seem similar much like German and Dutch, but underneath, there is a world of difference.
Czechs/Slovaks & Poles share some visible similarities, but Czechs and Slovaks are by far the most Western European slavic nation, the mort progressive, most open, most cultured and most worldly.
Poland while gradually moving more west, is still quite isolated in reality. While there are many brilliant Poles, there are still a great number of people with the faux-gangster villager mentality which damages the Polish image frequently.
This will change in time, but Poland seems to be still searching for its image.
Polish people often strike as as unsure wheter they wish to be respected for their talent and intelligence, or for their image/coolness and reputation.
Possibly the funniest thing I have found is that Warsawvians have the worst reputation in Poland, but they are easily the nicest and most friendly.
The people from Poznan and Lodz, all of those I've met, I would like to put them on a big space ship and sent them to a different galaxy.
They are by far the least useful, least friendly Poles and very frequently are involved in crime over here.
Lithuanians, Latvians, Estonians are somewhat closer to the Russian mentality while but most definitely moving in the opposite direction. (Lithuanian people are nice once you get to know them but appear quite rude if you do not know them).
Ukranian are closer again to the Russian mentality but Western Ukraine is moving in the opposite direction i.e. toward Berlin, Eastern Ukraine becoming increasingly pro-Russian and moving toward Moscow.
Belarus are very close and move toward unison with Russia, probably one of the only European countries which is actually moving into the Russian sphere of influence, mostly due to poverty.
It would appear that the Central Asian nations are very pro-Russian, but this is not unexpected considering the rise of China.
Then there is Georgia. A truely strange country.
They are a very small ship in a very big sea.
The tail wags the dog.
The men are anti-muslim, but as close culturally to Islam as one can get without actually being Islamic.
As a Western European, I often find their views on women very disturbing.
I have found them to be racist and xenophobic, but in truth I have only met their least educated people so it would probably not be fair to comment any more on them.
Then there is Hungary. Geographically it is in Eastern Europe, but they are totally Western European, they remind me of the Norwegians. Very nice people, many highly educated.
I utterly detest Romany gypsies, but find Romanian people quite friendly and a very different mentality from the slavs..
And so we come to Russia and Russian people.
The immediate thing that is apparent about anyone who has ever had a Russian partner or speaks the Russian language or knows their country, history and culture is that it is a land of polar opposites.
They have the richest and the poorest of people.
They have the smartest and the least educated of people.
They have the warmest and the coldest of people.
It strikes me as quite similar to the United States in this way.
The difference is that in the United States, a large number of people fall into the extreme categories, while in Russia, a large number of people fall into the middling and lower categories with only a tiny fraction at the top.
If we took societies such as the UK, France, Germany - these societies are generally well balanced in terms of class and very stable.
Russia is very unbalanced, and seems to be constantly fluctuating.
Change in Russia is inexorable.
Many Russian people are very warm and open and welcoming.
When I learned to speak Polish, many Poles would often laugh at me, try to belittle me or see my ability to understand them as a threat.
In general, Russians are quite encouraging and proud of the fact that you have chosen to learn Russian and seek to help you as much as possible.
It is a lie to say Russians are not family orientated. They are very highly family orientated.
So are Poles.
One of the most striking differences between Poland and Russia or Poalnd & Europe is the strength of Religion in Poland. I was truely amazed to see how seriously the young Polish took their religion, how many attended church services etc.
For someone who grew up during the biggest transition in Irish history which religion is now essentially defunct, it was quite a eye opener and give me insight into what Ireland must have been like 30 years ago.
All in all, I would say Russian people are the most friendly in Eastern Europe, although many of the least educated are patriotic to the point of nausea.
Poles and other Western Slavs would be a close second behind Russia in terms of friendliness, but Polish are generally the most provocative and most patriotic -somewhat understandably- as they feel the need to assert themselves, given their recent history.
If nationalitisim is a tool for brainwashing individuals and building armies, then Poland is civilian army.
The most frustrating thing about Poles for me is that they constantly need to assert themselves. They need to be the best at everything and Poland needs to have the best of everything. They are quite similar to the United States in this way, quite uni-lateral and arrogant/isolated. This is why it can be quite tiring speaking with a Polish man.
Polish women are generally more balanced to be fair.
It is quite ironic that Poles do not understand the mentality of the Russian diaspora.
The Russian mentality is quite similar to the Irish, in that, no matter what country you live in, you will always love the Motherland and always identify with it.
Poles mistake this for aggressive patriotism, but this is not true.
Only the least educated Russians are so openly provocative.
I think most Russians realise that their home country cannot support them and while they love and miss their home and their culture, it is now quite Russian to have 2 countries i.e. Russia and the adoptive country.

For the person who asked what territorial claim Russia has over Kaliningrad, you must read about the Potsdam conference.
You also need to understand the buffer which central and Eastern Europe was supposed to provide against future attacks on Russia.
Russia lost 28million people in World War 2, nearly 14% of it population.
Only Poland suffered more with 16% losses, and of course Lithuania which suffered the most and lost an estimated 20% of its population (a large percentage of these murders were committed by Russian communists)
