Hard to say. You are talking of 2 rifles I am very fond of and have had very little trouble with over a very long period of time.

Every rifle seems to need a trigger adjustment out of the box.

Any time you buy a new gun, especially if you don't see it in person first, it's a crapshoot. But not only with 700s, with everything.

I had 2 CZ 527s. Both NIB. Both 223s. The quality differences/issues right out the box was flipping amazing. I even posted about it on another site.

You never can tell.

Compared to many other brands/models, the 700 and 1500 are both relatively easy to fix/tweak if needed........
