Actually, I own both Winchester M70 and Rem. M700. They are probably as close to competitors as one can get...read Ford vs. Chevy here. I like my Win. .270 M70 Classic Stainless in that it has the following attributes:
1) slickest action b/t it and the Rem. 700
2) accurate rifle (easily less than 1 MOA @ 100 with 3 shots)
3) all steel bottom
Hwoever, I like my Remingtons for
1) accuracy
2) fit
3) finish
Therefore, I lean toward Remington but I do like my M70. Oh yeah, I have a Ruger M77 as well...Accuracy doesn't compare to either of the above nor does working the action compare. All of these guns are circa early 90s except the Remington which was made around '88. YMMV
