Your favorite sonata and Gershwin piece?

[vikktorious]

Hi guys, I need to pick a sonata and im asking for your opinions, it has to be around 4-6 minutes because my category in competitions this year is probably going to be max. 15 minutes and i have other pieces to play as well, so if anyone thinks of something please reply, i appreciate your help, thanks. And about the Gershwin, is he allowed on competitions? If he is, please tell me some of his best piano pieces ( max. 6 minutes again )
