I’ve used Linux professionally and personally for about 12 years. Yesterday was the first time I tried Wine after nuking Windows on my gaming computer. Pretty impressed with it so far, even if it will need a bit of tuning.
further, heroic games launcher isn't just for epic and gog games, you can install any exe. i use it for the ea games launcher because the lutris script was broken at the time. and in the wine manager in hgl settings you can choose either wine-ge latest or proton-ge latest (or whatever number version) as your default layer, which you can also change per game/app if you have trouble.
edit: and also you can set it to add to steam so you can still just use steam as your main launcher, for example on steam deck or using a media center rig in big picture mode.
I've switched a few months ago mostly for gaming, and here are few tips and issues I ran into, in case you run into them too.
Not sure what distro you are using, but I've run mostly into issues when trying to get NVIDIA and Proton working on Fedora. Just getting the drivers to work took a few tries, and I never managed to get stuff like cutscenes to work properly.
However, I then switched to Nobara (I suppose PopOS may also work), and the experience was wastly better, with everything working out of the box (I did switch to KDE Plasma on X11, since Wayland kept freezing on me).
I'm not sure what of the many changes Nobara does helped solve my issues, but I guess it may be related to it including Proton GE by default, which I recommend getting, and a slightly streamlined installation of NVIDIA drivers.
I also recommend checking out Lutris, instead of using Wine directly. However, I never really managed to get it working, aside from WoW, so your mileage may wary. But I have most of my games on Steam, where everything is working out of the box, so it wasn't that much of na issue. I only sometimes have to switch Proton version (by right clicking the game - properties - Force a specific version of compatibility tool).
