In the end I would choose the one that you enjoy more. Both are challenging and will require hard work and hours of practice. Technically I think the Ballade no. 2 might be a bit more difficult especially in the fast Presto con fueco sections. I've tried both pieces, but not formally learned them so sorry I can't be more help.

I personally think the Scherzo No. 2 is overall more romantic with a wider range of expression. I especially like the slow section. The Ballade no 2 is more virtuosic with with a more contemplative rather than emotive slow section.

Even though your teacher gave you the choice, if he/she has taught these pieces before they will know best what would work in your individual situation.
