Another Libra 2 owner here, it works great and it looks great too.

I'm currently playing Betrayal At Krondor on my old Celeron PC. I played a couple of chapters a few years ago but I left it there, so I've started again and I'm on chapter 2. Since the game is slow and mostly text based, I think its gameplay has aged quite well. I'm playing it with MT-32 sound and music thanks to my MT32-Pi.
I'm also replaying Undertale on my PS Vita, it looks great on its OLED screen.
I'd mainly play indie and AA games on it, alongside emulation.
How good is the trackpad? It's an important point for me. It's quite smaller than the Deck's and I read SteamOS still has problems with it, so I guess I would install Bazzite or CachyOS if it's fully functioning.
Edit: I just realized that you're talking about the OG Legion Go, not the S. The trackpads should be better than the Go S' small one.
Edit 2: But the OG Go is quite more expensive and outside my budget, so It's be Deck OLED vs GO S. The Go is a no-go (sorry).
Edit 3 (Is this going to end up being a saga?): I thought that I might buy a used Go, it's another option. The tiny trackpad of the Go S is a bit off-putting, I have a couple weeks to think it over.
I've been thinking about selling my Deck to get an OLED, or maybe a Legion Go S. I haven't decided yet, the Go S is more powerful but it has a higher res scree, so in the end they peform more or less the same from what I could gather. The OLED Deck is almost the same as the LCD model, but the screen tempts me.
I used EndevourOS with Nvidia for years but one day an update brought a black screen and decided to use something else (downgrade didn't fix it). I'm currently using Tumbleweed and it works well, but I kinda miss Arch... So I installed CachyOS in my Steam Deck.
