This is a good one, and not played often, but it may be a little too easy. I still stand by Op.2, No.1.

individual movements particular 1 & 2 rotate from grades 6-8 across various boards in the English (ABRSM) style system
If you are grade 6 under the English system I would recommend either of the op49 sonatas.
op 2 no 1 is harder than these. If the two op 49 ones are genuinely too easy for you (which I don't think they will be) then you can cruise through them, add two extra pieces to your repertoire and then move on to the op 14 sonatas or op 2 no 1
enjoy, they are wonderful works
