I have Axiom M22s and M3s (on different systems) and love them both. I've heard great things about the M60s.
What you have to understand is that for some reason there is a small group of Axiom haters on this forum. I won't even try and guess why, but I wouldn't rule out the Axioms based on a small response sample on this forum.
That said, I haven't heard the others and can't recommend one over the others. Speaker preference is so persoanal that if you could afford it I would recommend getting all three and comparing them. Returns of the other two would probably be about $200, but would be worth it to get the speakers that sound best to you.
If it helps, I'd say that my Axioms, and Axioms in general, are very neutral; with very little coloration. Some people like that, some don't. To get into an even grayer area, I've used them with Onkyo, Marantz, and now Yamaha amps and they sound great with the Onkyo and Yamaha, and just okay with the Marantz. (I haven't really figured out why, but the Onkyo and Yamaha were rought 80 wpc and the Matantz was 50 wpc; so maybe that had something to do with it.)
