The fit and finish on the Ruger doesn't hold a candle to the Remington, sharp edges, burrs, etc. Crappy trigger, most reputable gunsmiths won't touch a Ruger. That said, I have a Ruger #1 I bought in 1977 (1B in 22-250) that will never be sold.
I have or have had over a dozen Rem 700's, all are more than a few years old. While it's true that Reminton has had problems recently, even with these problems Ruger can't hold a candle.
Out of the box accuracy is next to none, with the exception of the new Savage's. I recently bought a new 12FLV in 308win. After break in the the groups have been averaging in the 2's and 3's with the best at .16". That is pretty damn good for any out of the box, under $500 rifle...
No One is going to convince anyone that one is better than the other in this post, however, I suggest you take a look at the annual sales of the Mark, against the 700, or ask a gunsmith to work on a Ruger, that's when you'll find out.....
