I have a Galago Pro 5 without the dedicated Nvidia GPU. It's a nice, lightweight, 14" laptop with an upper aluminum shell. I'm running Manjaro on it, and it runs great with a decent battery life (roughly 6 hours?) while programming.

The Framework laptop intrigues me but I ultimately wanted something less experimental.

System76 is a Clevo reseller, I don't think there is any added value other than supporting the company that makes PopOS but you might instead donate if you really want to. Framework in contrast is doing something more "revolutionary".
