They Both have there good points and not so good points.
Depron = its more ridged, Better for aerobatics because it does not twist and flex giving poor aerobatics, will crack with a crash, but is easy to fix with 5 min epoxy, inexpensive.
EPP = more flexible but will twist in flight, less likely to crack in a crash, more expensive normally, need to brace with CF if you want better handling.
This is IMHO
