I use a T3 and an SP100 for all my gigs.
Switching banks & patterns (T3) is a breeze, usually just a 2 button push, sometimes only a toggle up or down.
That's one of the main reasons I like it so much.
As for my SP100, my only changes on this unit are from Piano to String or a combi of both.
I've tried the Tritons, and first of all, I find the touch screens to be a pain, and even when I've finally got the hang of it, patch changes just take too long for my liking.
More often than not, I need to change banks and/or patterns on the fly, during a song possibly 2 or 3 times. The T3 has been great for this.

...Just my thots...
