For???
Not knowing that makes a suggestion tougher than it has to be and sometimes “neither” is the response for what a person has in mind. So...hunting rig, mountain rifle, stalking Cape buffalo, or ringing steel?
I’ve only handled a Bergara briefly, browsed specs, and read reviews. I own and have shot a few 700s. The Bergara looks to be a better iteration but I wouldn’t bet my money (or your’s) on it. If pressed I’d likely chose a different option all together (for hunting), but only as a preference.
