IMO the Strymon stuff sounds great. Highly tweakable too. With guitar I avoid option overload (for example, my current fav fuzz pedal has one knob) but that's just me. With keyboards I love setting up a sequence or arpeggiated pattern and going whole hog on it with effects. I use an old Eventide gizmo and various Moogerfoogers for this but if I were to replace the Eventide I could easily go the Strymon route.
