It's more about the design of the open-world, and what you can do in it. GR's map is larger, with more prohibiting terrain, and several biomes for variety. It has air and sea vehicles, and parachuting. It has random encounters in the wild, which shouldn't even be worth noting, but it is since MSGV doesn't have any.
I'm not saying MGSV is shit, and I'm not saying Breakpoint is a great game. It's still a bog standard 7/10 Ubisoft open-worldathon, but I'm having way more fun larping in Breakpoint than I ever did in MGSV. And I keep going back to it. The real guns and CO-OP definitely help.
