The Win Mag delivers more energy down range and will drop most any deer in its tracks if you do your part. The Rem Mag isn’t very far behind and will drop deer in its tracks if you do your part. I’ve had both and killed many deer with each, i now own a 7 Rem mag and shoot 120 ttsx, kills like lightning. The Rem mag has less recoil and will do the job. The win mag has more recoil and more energy and will do the job, ammo is usually a little more too.
