I've made this comment before, but to reiterate, I think that consoles are generally a better solution for competitive multiplayer games.
Consoles were designed from the ground up to be locked down. PCs were designed to be open and modifiable. Trying to figure out ways to jury-rig a PC to act locked-down is always gonna be an uphill battle.
Also, since this is for competitive multiplayer games, consoles also provide a level playing field on hardware. No pay-to-win "buy this hardware to get an edge" stuff. There's a whole industry of PC "gamer" hardware sold using basically "pay to win" marketing.
PCs are nice because they're open. That lets you make one faster or prettier or use any input device or rig up macro software or mod games, fiddle with memory or whatever. And that's a good thing for games that aren't competitive multiplayer games. You can play the game however you want, and it's not like it negatively affects anyone else. But that same characteristic that's an advantage for non-competitive-multiplayer gaming is a drawback for competitive multiplayer gaming.
For competitive multiplayer gaming, you want a platform that provides equal footing for all players as much as possible and is hard to modify, and that's what consoles do well.
