Debian on a base model 2013 MacBook air checking in. Runs better than it ever did on Mac OS. Battery life is still fine. I did have to use proprietary drivers for some things (wifi and webcam) but other than that it was pretty much plug and play.
Lots of replacement parts are on ebay for cheap, and there are a lot of repair tutorials on YouTube (and piped.video) I replaced keyboard and trackpad cheaply, and some of the internal cables.
As far as drawbacks, if you have to replace the storage or or logic board, those are expensive. I have a sound issue which I haven't been able to fix and from searching around it looks like a logic board would be required. Bluetooth headphones work fine though so I'm just dealing with it.
Yeah I've never had a missing driver problem with a windows install since maybe windows 7. I even moved a hard drive with a windows 8 install from an Asus laptop with an Intel cpu to a custom build desktop with a ryzen cpu without having to change any drivers. I did have to reactivate windows because of the hardware change but that's it.
The included drivers are often providing less performance than updated ones from the vendor though, so it is recommended to download those in some cases, specifically nvidia. But most gaming laptops will have a vendor provided update center to manage all of that for you.
I like Linux over windows for a lot of reasons but this post is a bit silly.
