In my own experience, I tend to use rewired devices less because they aren't as quick and simple to hook up as plugin instruments. Also, if you forget to close them out, PT gives you a nasty error when exiting. Maybe the extra time in setting up a rewire device is worth it to you. I have to admit that I did like the demos I heard of GA3. fxpansion's vst-to-rtas adapter might get rid of the need for rewire. Another option to consider: Drumcore. I've been using it for more things than I'd care to admit. Between that and Stylus RMX, I've been covering a lot of ground - but I always want more. There is now a DrumCore LT which is free. You then add famous "players" for around $70 each (discounted) in their "DrummerPaks".
