Well, I'll give you some input from what I've experienced.

Accuwheel: very easy draw and letoff, but kind of a "mushy" back wall. Since it is a wheel and not more of a lobe-shaped cam, they are rather slow.

Command cams: you'll notice some more slope going into the valley on the draw. Much firmer back wall. You'll gain more speed vs that accuwheel.

We had the accuwheels on my girlfriend's bow. She liked the ease of draw, but could never get used to the spongy back wall. She has shot better now that she is shooting command cams. So if you do like a stiffer back wall, you won't like accuwheels. just my opinion.....
