My primary gripes with Lutris are:

1. it doesn't (at least recently?) always do a great job of handling multiple displays, either launching games on my second monitor, which I orient vertically or getting confused about which monitor to use and switching back and forth until eventually the instance (but not the Lutris client) crashes

2. I find myself getting into launcher hell where I'll use a different wine version for one game and when I switch to a different game, it's using this new wine version and stops working

Not sure if Heroic solves these issues but I would try it again (didn't have any luck setting it up initially) if it does

I can answer the first on at least:

If you are using KDE then there is a global Window rules setting and Heroic actually obey those rules, so you can force to launch a game always on X display, always minimized etc.

I've been using Lutris on i3 with multiple monitors. Enabling gamescope has been extremely helpful. I just get a window that tells the game to render at some fixed resolution, and it is happy to scale fullscreen or any size. I've been using i3's fullscreen toggle, it goes to the current monitor, or I can move it to another with my regular i3 binds.

It looks like gamescope has it's own fullscreen shortcut (super + f), but people complain about it about it going to the wrong display. Maybe your window manager offers a more consistent full screen option like i3 does.
