No huge advantages to either, really.

The Tikka has a better trigger & barrel...and might be more accurate out of the box on average than the Remington. But theM700 actionis easy to work on, and accurizing it should be no problem.

The Remmy has a nicer stock, and IMHO a nicer feel. But the Tikka is a very well-made rifle, as well.

Pick the one that feels most comfortable in your hands and don't look back. Both will perform admirably!
