I definitely think that the Axis is a good choice, it is the arrow that I shoot and I have no complaints. You will probably have people tell you otherwise, but through 2 seasons they have been good for me.

As for the grim reapers, i've heard people being mildly satisfied with them. If you like mech heads, look into NAP Spitfire, Rocket Steelhead, or the Eastman ST3. Personally I still feel that you can't beat the Slick Tricks but they are not mechs. Good luck in your decision.
