I've made the complete switch recently (been using Linux on and off for years, including WSL as well) after my pleasant experience with the Steam Deck and it's been fantastic, but not without issues. A recurring issue over the years of trying Linux has been WiFi drivers; I really can't afford to have WiFi not work as I can't run an Ethernet cable to my computer room. I get that Linux heavily relies on volunteer work, but a broken WiFi driver due to an update is a big roadblock.
Beside that though, I'm happy to have left Windows behind completely.
