I hate trying to pick favorites when it comes to Chopin. Yes, #2 is the most popular - I grew up listening to my mom play it - but I don't think that I would call something so good "overplayed" ...I picked #1, but I don't know that I would call it atypically violent for Chopin - he's got a lot of good violent stuff.
Shall I make a list? Most of it is mixed with delicacy, but so is that Scherzo - the middle of it is absolutely lovely. If I'm forced to rate them in order, I would say 1, 2, 4, 3...but it's soooo close. I love them all.
I might say 2, 4, 1, 3 tomorrow...I like #3 (of course, it's Chopin!) but I think I will always like the other three more.
