I've heard the Rocket RS150...if it sounds anything at all like the RS250, then it's one of the most "laid back" speakers ever made. Voices in particular sounded VERY hollow and distant. Axiom M22ti's are just the opposite. Voices will sound like they are right in front of you.
Which is best for you is a matter of opinion. I prefer the detailed, clear sound of the Axioms, but many people like the laid back sound of the Rockets. You should listen to both - you'll love one, and hate the other. I don't think it's possible to hear a Rocket speaker and an Axiom speaker and like them equally. They're just too different.
