JohnWPB......that is a true sign you have WAY too much time on your hands!
Streetdeck fan here, but I gotta jump in with the other guys. For customizing ability and widest range, my vote would be RR too. That is IF you don't mind taking a lot of time getting everything you want to work together. It is definitely (by FAR) the most versatile.
RR is the closest to being the "killer" front end.
