The cz is a nicer rifle out of the box. If you want to tinker and customize, the remington has a lot more aftermarket available. In addition, pretty much any gun smith will work on a 700.
Honestly, though, I think the new winchester 70's are the nicest of the non custom factory rifles right now. Since FN bought them, their rifles are VERY nice. Every bit as nice as the pre 64's. If you get a chance, check one out.
