I think Bill’s is a push feed too.
As for feeding I would say both are acceptable if fixed. The 700 DM of mine is finicky. It feeds about as well as your old Mashburn PF70 that Bill has now. As in, it will feed if you work the bolt with authority quickly, but it pushes the round to the right if you move too slow.
My other 70s and 700s all feed without issue.
IMO, nothing feeds like a M70 (except a 03 Springfield, which is basically cone-breeched the same way - imitation, flattery, and all).
I have 3 Pre-64s and one post 64 full length classic, and they are sweet, but I recently got a stainless 270 WSM which has a 3.00" magazine and that dang thing will cycle and feed a magazine full of EMPTY cases, those short, fat, steep-shouldered 270WSM cases, in and out of the chamber slicker than owl snot. Feeding just doesn't get any better than that, IMO.
The Rem 700 is a darn fine action and probably superior in inherent accuracy to the M70, but feeding-wise there's no contest. When it absolutely positively has to go BANG, the second (or third, or forth) time, use a model 70!
Cheers,
