What a can of worms. This is like asking what the best brand of beer is. I do not have a lot of experience with the 7, other than a good friend of mine has a Browning. Lord, does that thing kick. He is running 160 grain Partitions. Must be that particular rifle that makes it boot like that. I have had much more experience with the 300's. I am a 300 H&H guy myself, but have loaded a lot of WinMag ammo for friends. As far as I am concerned, the majority of the 300's (H&H, WinMag, WSM, SAUM, Norma, 30-338, etc) all do the same darn thing: 180 grainer at 2900-3000 fps, and all are pretty darned accurate. When you get into the Ultra Mag and Weatherby class, then the speed goes up, as does the recoil (and ammo/component prices). The 7 vs 300 debate is simple: get what you want. Find guys that have them and ask if you can shoot them at the range sometime. For every 7 Mag guy you find, you will find a 300 guy. I cannot say that the 7 kicks noticeably less than the 300, as the only 7 I have spent time behind boots me aplenty. But as I said before, it may be that one rifle. Guys that have 7's love them, and will tell you that recoil is less and performance is just as good as a 300. They are probably right. Us 300 guys will tell you that recoil is not that much more than a 7, and performance is better due to the same speed (7mm, 160 grainer, 2950 or so fps vs 300, 180 grainer, 2950 or so fps) with a larger caliber, heavier bullet. I have shot a lot of animals with my 300 H&H, and if I hold well, the rifle performs well, no complaints. I run 200 grain Partitions in my rifle, vs the 160 grain Partitions that my friend runs in his 7. And guess what? He has shot just as many animals as I have, and if he holds well, his rifle performs well, no complaints. Despite my preference for the 300's, you really can't go wrong with either. Good luck.
