Fit and feel are the most importantconsiderations imho whenselecting a firearm, so I suggest you need to handle them both and see what you like best.

I prefer the 700 personally because of:
Fit/feel
Trigger and adjustability
Non Mauser action
Aftermarket products more plentiful for 700vs M77

Though what I or others think in reality means squat if you don't agree. Both are good rifles and have legions of supporters. You need to choose which group yo join. I am willing to bet after some touch time you will find favor in one over the other.

Good Luck
