Krakow or Warsaw - which is a better place to work?

hello. new to this forum.
I may have the opportunity this year to work in Krakow or Warsaw! Ive been to Krakow and loved it!
How does Warsaw compare in terms of history, nightlife(i love jazz and house music) and general other things? I do like a busy city.

I've been living in czech rep. and Brno the 2nd largest city is totally different compared to Prague. Is it like that in this case?

Also, what areas in Warsaw are good for living (centrally) and how much would i be looking to pay in Zloty for a 2 bed unfurnished apartment on average? so i know i dont get ripped off like in CZ. they know you are foreign, and everything is more expensive!lol

Which one would you choose to live in and why?

THANK YOU ever so much for all youre help!! I cant thank you enough!!

I've never been to Warsaw...
First you know what Krakow is like as you've been there.
Warsaw is maybe less interesting, historically, as it was almost totally destroyed after WW2. But the center was rebuild and is said to be great... :)

The nightlife may be better in Warsaw though, because the city is much bigger...Can't really tell.
