I would have to suggest basing the purchase on your physical characteristics and the largest game you intend to hunt.
Personally, I'm not so tall (only 5'-6") so I find the shorter bows are much more comfortable to cock. The largest game I'll probably hunt is the whitetail, so power isn't a concern - any of the Excaliburs are more than enough. I chose the Phoenix because it is still compact enough to be easy to cock and I prefer a camo finish simply because it looks better to me, the deer could probably care less.

I started many years ago with a Vixen (the black finish) and it was all I really needed, but I let the talk of "faster is better" get to me and sold it and bought an Exocet (175#). The Exocet was too much for me to cock comfortably (the draw length, not the weight was the problem). When the Phoenix was introduced I grabbed one up ASAP! The weight of the Exocet and the power stroke of the Vixen (at that time) and I was in love!

I've owned the Phoenix for three seasons now, and have no desire, or intentions, of ever letting it go! If it were lost, stolen, or destroyed tomorrow I'd buy another Phoenix! Every deer I've shot with it was a complete pass-through, and every one was a good quick kill. My only failure was a complete miss on one opening day of this season because of a scope failure (TenPoint scope) but a Vari-Zone solved that problem and I'm 2 for 2 since!
