Hi guys,
Need some unput from some more experienced Beethoven specialists

I'm choosing pieces for an exam and theres a choice between Beethoven, Mozart and Haydn sonatas. I'm leaning towards beethoven because i have looked at the other two and they all seem to be faily short and i have to fill half an hour.
Because im not toooo familiar with his sonatas, except for the classic ones (moonlight etc), i was searching for one that is fairly underplayed 1) because i dont want to touch a classic and perform it sub par and get slammed by the markers and 2) i think its good to stand out from the crowd and play something they dont hear too often.
SO, after that long winded explanation here is the list of choices of his sonatas.
F minor no1
C minor no 5
F major no 6
c minor no 6
E major no 9
G major no 10
B flat major no 11
A flat major no 12
E Flat major no 13
D major no 15
F major no 22
F # major no 24
any input would be appreciated

difficulty is not really an issue as im sure im going to struggle equally as much with any of them haha.
