Polish sponge cakes/biszkopty
To me they're what we in the Isles would call 'trifle sponges' and we would never eat them as a biscuit. Ours are oblong in shape and they're used for making certain kinds of cakes or desserts like trifle especially because they soak up sherry or other liquid very well. Not a fan of herbatniki either. They are mostly too sweet and not very good for dunking! I know, they're supposed to be crispy but dunking is one of life's great pleasures.

Same here. Rich Tea was considered 'a plain biscuit' but I liked them. I still do. Very comforting with a cup of tea if you have a headache or have had an upset tummy. You can get Rich Tea fingers in Dealz. Not as satisfying as the proper round ones but any old port in a storm! Nice were very sugary and old ladies seemed to love them. I remember them being served to old lady visitors with a glass of sherry.
Did you have Lincoln Creams in the UK? I really liked those. They were another sweeter plain biscuit considered suitable for the weekday biscuit tin. We only had 'sweet' biscuits with cream fillings on Sundays.
The only biccie that I truly detested was Marietta. No greater disappointment as a child than going visiting with your mother, out comes the biscuit tin and you're offered a Marietta :( I suppose Arrowroot were worse but they never really caught on in Ireland.
