I've had several Critter Gitters over the years, and a few Dwyers. Very difficult decision. The Dwyer index grip is more indexed than the GN, and the Dwyer Dauntless is more of a hybrid with greater deflex/reflex than the GN. Both are extremely smooth, solid bows. In a short bow, say 60-62 inches, I'd go with the Dwyer as opposed to the CG. It's a toss up at 64 inches. This is for a 28-inch draw. Bamboo laminations add to the performance of either bow, and that's what my most recent version have. I know GN charges extra for bamboo. I don't think Dwyer does.
Both are excellent bows. Good luck.
BTW, I have a Critter Gitter Special listed for sale. It's in as new condition. If the specs work for you, it's a few hundred dollars off the new price.
