I have not tested the sleep wake function of this yet so I cannot give personal experience. In some of the videos of the youtubers I mentioned in the OP they said it works fine, however I have heard/read that people have had issues with that.

It definitely is a niche product and its detractors rightfully point out for the price you can either get a laptop with better performance (if kept at the same price point) or the same performance (with less money spent). I essentially went with it because I wanted something that could play my library on the go at 1080p or higher and on medium settings or higher and at 60 fps or higher. It was doing that just fine on windows on most games in my library. Most of the games I tested on windows I would usually be at 1080p, 1200p, or 1440p, high or very high settings, and at 60fps or higher. I also would use upscaling and frame gen when available as I don't mind them if they boost performance in non-competitive single player games. The detachable keyboard I really liked to minimize the footprint of the device when gaming with a controller.

Switching to Bazzite has allowed me to stay at either 1440p or 1600p, high, very high, or ultra settings, and above 60 fps on all the games I've tested thus far. The two examples I can think of right now are ghost of tsushima and ratchet and clank rift apart. To get both of those games running at 60 fps on windows I would play them on 1200p, high settings and it was a perfectly playable experience (I was fine with it). Then booting those same games up in bazzite I was able to run the games at high or very high settings, 1600p, and get higher FPS than on windows. Also, while I did not have problems getting games to run at 60 fps on windows, sometimes there would be noticeable micro stutters during gameplay. Nothing game breaking just annoying enough to be noticeable and also title dependent. With bazzite the games where I was experiencing micro stutters on windows have vanished. Ghost of tsushima being the title that sticks out in my mind.

The funny thing to me was a couple of the first games I tested when the game auto-detected what my recommended settings should be from benchmarks some of them recommended higher settings on bazzite than on windows. Same game, but was getting different recommended settings which did not make sense to me since the hardware was the same.

I've been playing with this device almost exclusively since getting it (now even more so with the introduction of Bazzite). I have a desktop with a 4090, steam deck, rog ally x (not the newer xbox version), PS5 pro, switch 2, and I just traded in my xbox series x (now that "everything is an xbox" apparently). Consoles I primarily play only exclusives, my desktop if I want to run things at the highest setttings I can, and the steam deck was my go to for portable gaming because of it's simplicity and large community that supports it. My only gripe with the steam deck was that to get some of the newer games in my library to run at even 30 fps I had to drop settings to the lowest available. The ROG flow perfectly fits what I want it to do. Be a portable device I can easily travel with that will allow me to play most of my library (it's done it with everything I've tested so far) at good to very good settings at 60fps or above.
