I'm with Robby on the Axe. Been using them as team guns for the last 3 years and they are excellent. However you may have to stretch your budget a little to buy one.
I cant comment personally on the other guns as never owned them or used them, but IMO go for the Axe.
If you need any advice on them then let me know.
BTW, I have some Ex Team Guns available if your interested.
