I would definitely give Bazzite a try. If you are looking for stability and a set and forget OS. If you don't like it you could always try something else.
If you are looking for something to tinker with and change things like manually changing packages or messing with services you probably want a more traditional "non-atomic" os
Don't let talk of the filesystem being "read only" scare you. You can still save files to your desktop and documents and stuff in your user folder.
In windows terms it's more like imagine C:/windows being read-only so you can't break your system. You can still write files to other parts of the drive, but it prevents you from messing up your install (some people like this added layer or stability, some don't like it because it makes tinkering with your system harder)
An atomic OS is kinda like a phone OS, in the sense that every version of iOS 26 comes with the same version of Safari and the same libraries. It makes it so any bugs are reproducible and easier for the developers to track down. Packages are pinned to the OS version. (For example all installs of Bazzite 20260101 will include Nvidia drivers 590.44.01-1)
In a more traditional Linux distro because packages can be updated to whatever version if you install Ubuntu the version of Nvidia drivers is not tied to the OS version. You could have an install of Ubuntu 25.10 and could have a completely different Nvidia driver version from someone else on Ubuntu 25.10. This could make bugs harder to trace because you could have the same OS version but different packages. Think of this like even though you and a friend could both have (Windows 11 25H2 installed you could have different drivers installed)
As for updating Bazzite generally auto updates once a week in the background. It requires 0 manual intervention and keeps your packages and drivers up to date. You can turn this off if you wanted to. Since it uses a "image" based approach (again imagine upgrading from iOS 26 -> 26.1) it is able to save the previous version of the OS. So if the upgrade broke something you can roll your system back to a known good state with a single command.
If you are looking for something that's set and forget I would definitely give it a try.
If you want to tinker with it and figure out how Linux works I would probably try arch or something
It's funny. I feel like with the switch 2 Nintendo finally listened to the fans who were saying they just want an incremental improvement. Just make the switch with a better processor. But they really just got too greedy with it and made it an incremental improvement in the worst way possible. Paid online, $70 games which never go on sale, paid switch 2 upgrade packs, LCD screen, digital download physical games.
It's an incremental upgrade done as horribly as possible, it feels like people are struggling right now and Nintendo is trying to extract every dollar out of customers then wonders why the console isn't doing well.
For me it's a hard sell because like at that price why wouldn't I just buy a steam deck. I don't have to buy any new games, I don't have to pay for upgrade packs to have my games run on it, I don't have to pay for online services. I'm not going to have to rebuy games if I buy a steam frame or steam machine. It also has seamless save transfers, and steam is famous for its sales.
It's just funny because I feel like people were asking for a switch with more power but now that it's here like why would you buy it over a steam deck.
Also to top it off Nintendo's lawyers are aggressively going after emulators, streamers and modders. Why would I want to support a company so hostile to its own community
