I know you mentioned System76, but I thought an anecdote of the gazelle 15 I bought during covid would help.
It's the 2021 model with a 10th-gen i5, 16GB DDR4 RAM, a cheap 256 nvme SSD, and a GTX 1660ti for $1300. Very good laptop that I've used the hell out of since then. Has an excellent 120hz IPS panel (1080p) that's just buttery smooth, and using pop_os on it has been very stable, even with all their firmware updates including the switch to coreboot for their UEFI. Plays all the games I needed to when I was away from home, and the keyboard is one of the best I've typed on, on a laptop.
Now my only issue with it, is the shell, which was not entirely metal as I was led to believe. It's got some pretty cheap plastic for the bottom side that feels like it will crack if dropped even from a short height. I THINK this has been changed in newer models though, as they were using rebranded Clevo laptops for their chassis. Still, I hate that it's half nice brushed aluminum looking metal and half brittle plastic housing a VERY (at the time) expensive parts. It's the only flaw
Does this change my mind on buying System76? No, because I've seen their newer stuff and it's made leaps and bounds from my laptop in just a couple of years, and I absolutely plan on buying a beefier Oryx Pro or something on the future. They're excellent Linux machines
