I vote for the RTT....but thats because Im biased! I just got mine and I NEVER put it down......of course It doubles as my diaper bag too....I think it all depends upon what you carry around with you....the RTT works for me because there is more room within the handle to slip over my shoulder!
SO....which one did you keep?
Heres a pic of mine.....im 6'0'' for ref....
