Each of them are capible of shooting sub MOA (given the "right" ammo) from the bench.
It's all about what "features" YOU WANT in a predator rifle.
I like synthetic, stainless steel with a detachable box magazine.
If I'm going to walk with it (shooting sticks in hand) - no more than 7lbs.
If it's a short walk to stands, then I mount a harris bi-pod on it.
For a carry gun I use a Remington 700 SPS DM (not stainless however) in .243 (75 gr.V-max), if I'm expecting long shots or on windy days. I carry a Bogg pod tri-pod.
For stand hunting, I use a Savage 16 FCSS in .204 (40 gr.V-max) with a harris bi-pod on it.
