I haven't made the flip over yet. Reasons:-
1. Breverb - I just can't seem to get the effects I want out of it. I've tried but I get fed up wasting time and load Pantheon or Ozone5's reverb module.
2. It's too easy to have the wrong track in focus - 'why isn't this doing anything?'
3. I find them fiddly. Also, the curves on the EQ only move with massive (I'm talking 6"-10") drags with the mouse. I wish there was some way of changing the 'gearing' here.
4. I've got FabFilter's L, C and Q modules and for me nothing beats their quality and ease of use and GUI information.
Chacun à son goût, etc.
