Curious what exactly you didn't like about the 737 training? Thought the CBT had modules that could have been better, scheduling could have been more streamlined, an awful lot of time spent on RNAV approaches instead of ILS at speeds ATC usually requests, and not incorporating ACARS into sims. On the other hand sim instructors were almost all great, support staff was helpful, and breakfast burritos were awesome, but they are gone now.
