I guess it depends on your budget and flying spaces.
Flying whenever the mood & conditions suit you (ala UMs) means you learn faster.
Having fun whenever the mood & conditions suit you (ala UMs) means you get more opportunities to have fun.
Aside from that, bigger planes are fun too. Just depends I suppose.
Here's a post where I lay out a general case for Ultra-Micros:
For my own learning, I went from Champ to UM T-28. I'll get a bigger plane once I've learned as much as I can on the cheaper plane that lets me fly more often and shrugs of damage so well. And... I'm sure I'll keep my UM T-28, just for fun!
