One thing I really DO like about Uncanny X-Men is that it's not really a team book. It's just about mutants surviving and doing what's right for mutants. And of course, whatever shit people who hate the x-men get them caught up in.
As a result you don't end up with really arbitrary and boring "teams" that can't ever be adjusted. You have as many mutants as you need being used constantly and being put into combat when it best suits them. Basically I really like the San Fran x-men a lot.
