I'm in the 94 league, but my true love is 93 and quite honestly that's all I play with friends (on the actual console) and when I just feel like playing by myself. I play it so much that I feel I've mastered it much better than I have 94 (I have always been terrible at goalie control for example, never could get used to holding down the b button and prefer to play without having to do that).
93 is very different from 94. Different bounces, etc. I'd love to join your 93 league whenever it starts. I have never considered joining another league besides gens classic 94, but a 93 league I would definetely join.
