Cheating is definitely a problem in SF6, but it's a lot less of a challenge dealing with it due to match duration. You generally move on to different opponents fast enough, unless of course you're at the highest ranks.
Still agree that kernel level anti-cheat does nothing here, and I also won't be buying it due to that reason.
IW4x exists if you want to mod the original MW2 with dedicated servers, been meaning to try it for a while so can't comment on its popularity
