Not GP but I'm very happy with mine. Can't speak for every model but I've got an old 15Z970 with 24 GB of RAM (from 2017 I think).

LG Grams aren't cheap laptops. They don't have the retina display. But they're nice, lightweight (lighter than Mac laptops) and overall feel good.

I'd say it doesn't feel as polished as the latest Mac laptops but it feels way sturdier. My M1 Macbook Air always felt like it's screen was brittle: some porcelaine to be manipulated with the greatest care or it'd break. And break it did, after 10 months, seemingly for no reason.

While my 5 years old LG Gram is still going perfectly fine.

I use it every time I'm not at my beasty desktop.

I have one too (17Z90N), and it's pretty nice, as laptops go.

~10h battery life on Linux with minimal tweaking, decent keyboard and touchpad, huge screen (I've tried to use the tiny laptops that are popular these days, and they just do not work for me).

Things I don't care much about and so explicitly won't review: camera, internal audio (I only ever use headphones), battery life when closed (I just go put it on my desk and plug it in when I'm not using it)

My one major complaint is that the edges are unreasonably sharp. Seriously, I don't know who designed this thing, but they apparently use laptop keyboards very differently than I do. I have been considering filing them down.

I also got it on ebay for what I now realize is significantly below the price it would've been new. I don't think it's worth $1800, but I don't think any (personal) computer is worth $1800, so adjust your weighting of this opinion as desired.
