I have a Surface Laptop 4 with an AMD processor and 16GB of RAM. I'm extremely happy with it, though I'll concede that the build quality is a click lower than a M1 MacBook Air (two of the rubber feet have fallen off of mine, being my main ding against it) and nobody can touch Apple Silicon's battery life. But aside from that, it's definitely in the same arena for build quality as an M1 MacBook Air (my wife's daily driver, so I'm not just saying that out of ignorance) with, IMHO, a better keyboard and a touch screen if you're into that sort of thing. Oh, and the facial recognition unlock is the best. I've had zero issues with stability—Microsoft pays more attention to squashing Windows bugs on their own hardware, it seems like.
Surface Laptop 5 has been out for about a year, but it was a totally microscopic incremental refresh. That means the Laptop 4's have dropped in price a lot, even though it's still 95% the same laptop.
My exact model of Laptop 4 can be had on periodic sale, refurbished on Woot.com for ~$700 or less, which is a screaming good deal IMHO for what you get. You could almost get two of these things for the price of one new M1 MacBook Air once you factor in the (IMHO mandatory) RAM upgrade.
