It definitely is much better than before and has some niceties over the flatpak. Games are added to your app launcher, no need to fuss with permissions if your games are stored on a secondary drive, and you can optionally tell it to use more up to date mesa versions.
Though personally I am sticking to the flatpak. I like that it has less filesystem access by default. I also encountered some irregularities with the snap when using Black Myth: Wukong's benchmarking tool: https://github.com/canonical/steam-snap/issues/403.
