That's what I've heard also. Even before the M1 though it was really good. I used to have a Macbook Pro at work including a VMware emulator running Windows side-by-side with MacOS, and the Windows stuff ran faster on my Macbook than they did on some native Windows laptops at the time. It was impressive.
I went to AMD for a little while in the 90s but I went back to Intel when I saw what a power hog and heat source those AMD chips were at the time. They've gotten far better since then but that memory still sticks in my head.
