Lutris does most of its updates from within the app itself, so it only really needs packaged releases when there's an update that can't be done from within itself.
Heroic Games Launcher has been improving a lot, now having install scripts like Lutris, more platforms available, and a lot less janky than it used to be.
Bottles I don't have much experience with for games, but it's a really good program a lot of people use, and if you like Libadwaita apps it's pretty amazing.
If you only need Lutris as a game launcher (rather than the install scripts, WINE/Proton-GE, and such), Cartridge is a nice little GTK4/Libadwaita launcher too. But it is just that - a launcher, nothing more.
another +1 for Heroic. Lutris never worked for me, would only install games but not launch them, and I'm not skilled enough to figure out why. Almost certainly something specific to my setup. But Heroic makes things easy-peasy.
And yeah, if Heoric doesn't work for some reason, Bottles usually will.
