I personally prefer APO3 over CRF3. The APO3 outweighs CRF3 with it's just sheer usefulness overall. Granted the only 16.5% uptime as opposed to 50% uptime is MASSIVE, but considering what APO3 does, even with just 6 points in AP, I would take it any day of the week. As for the other APs? Tbh, Beta 3 is mostly useless outside of PvE (until your target gets a subnuke on it, after which... ME GUSTA!!!!), and Delta 3 is just insanely useful, but hellishly rare.
