Flawed logic - an Intel Mac would never be better than an Intel PC for gaming - only at best similar. An Apple Silicon Mac could theoretically become much faster than an Intel PC. At that point I’d suspect Windows to push Arm aggressively though.
Having owned an alienware pc, one way an intel mac would be better is it is unlikely to crash every 45 minutes, and if it does crash, and you call the manufacturer for help, they are unlikely to tell you they can’t help you because once you install any software it isn’t their problem anymore.
So I guess that’s actually two ways.
