Personally I use Bazzite and I think it is great.
I operate four PCs in my day-to-day, which may seem excessive, but I choose to solve most computing problems with PCs (no smart TV). My HTPC, which I drive with Bazzite, primarily serves as a fireplace/ light media/ light gaming setup. Bazzite is uniquely well configured for this purpose. It brings the stability of a Fedora-based, Atomic OS, but leaves behind the codec and media issues Fedora can introduce. The tinkering one would generally need to do with Steam comes pre-configured, like you may be used to with SteamOS on Steam Deck. ExpressVPN works, but requires terminal in my configuration (I believe I could operate it through a GUI if I were so inclined). Bazzite does a great job of being configurable to serve TVs that need scaling and safe zones.

A friend gave me their old gaming laptop, it was mid-range when she bought it, and she didn’t use it anymore. I stuck bazzite on it, and I really like the experience! I’m no stranger to Silverblue, so some of the atomic host stuff was already old hat to me, but I was impressed by how much worked straight out of the box. It’s kinda become my retro gaming go-to device.
Yeah that sounds like a basically perfect use-case.
