I still have a Montana. I don't have a lot to compare it to, but here are my thoughts:
Pros - As other's have said, it's bombproof! I'm rough on equipment, and it takes it all. I shot it well out to 20 yards. It's quiet (to my ears).
Cons - As other's have said, the grip is not that comfortable. I did notice some shock (never enough it was uncomfortable, and I kept the stock string on it). I didn't like the amount of arrow drop past 20 yards. Some don't mind this, but a slightly flatter shooting bow gives me a little more confidence.
If I was starting over with the info I have now, I would look into a Kanati or something like that( again, just me).
Go shoot one! Most of the two largest sporting goods stores carry them in stock (right handed).
