I think that for the combination of looks, performance and selection that Rem offers in the 700 line, there is no real comparison. And I own a Win 70 and an A-Bolt, nary a 700. Well, maybe Ruger......
I can't speak to new-rifle quality issues as I seldom handle or shoot new rifles, but I've wanted a Mountain Rifle for years; the only reason I bought my .280 A-Bolt is that no one in Alberta had a .280 Mtn left in stock. I still may get me one in .260 Rem.
My only grievances against Remington are that they haven't pushed the .280 or the .260 hard enough by offering them in more rifles for a longer period of time. Maybe Ruger could teach them something.
Tikka rifles are excellent quality and dollar value IMHO, but they don't offer the selection of models that Rem does, and I don't personally find them as pretty as 700's. I realize that looks shouldn't matter much, but they do to me.
