I play both 6max and full ring. Admitedly, I tend to play more 6max because the action is faster and I don't have to wait for what seems like hours between each hand. I generally multi-table 2-3 tables these days (rarely 4) and I usually play 2 6max tables and 1 full ring table; there's more money to be made at the full ring by camping and waiting for the right hands to play but still nice amounts can be made playing aggressively at 2 6max tables (IMO)
