I think the b minor op.20 is the easiset Scherzo, it has so much repetition; 18 pages long but only 8 or 9 of material! I would say the E major op. 54 is the hardest,a very elusive piece, hard to get a handle on IMO.
This piece will be good for you Triton in view of your current rep, it's the perfect step up.
