Ok, here's the rub...
Active accel > rush of knowlege. Rush of Knowledge + Rollover cap > Active accel bonus (all at same level that is).
But going over your level in xp isn't worth just levelling Active accell. It is better to do aa first then rok then rc. That doesn't count group acumen either. ga will give a good levelling bonus, but won't affect trophies. All depends on you build.
Personally, I level (to my level) in this order:
al
pa
aa
rok
ga
rc
