Not quite the same ballpark yet, but I sincerely hope they get there. System76 are rolling their own distro - Pop!_OS - and their own tiling window management add-on - Pop! Shell - both of which I've switched to using even on a non System76 machine. Star Labs test with various Linux distros, but they haven't shown quite the same deep involvement with software, community and ecosystem yet. But that's no easy feat!
I can't comment on build quality- I've never laid hands on a System76 system, as alluring as they are! The Star Lite is pretty damned nice, feeling a bit like an 11" MacBook Air but just a little bit more sensibly proportioned. I haven't seen many - actually good - 11" laptops and I feel they've hit that particular niche pretty well.
The Star Book and Galago Pro - both with i7-1165G7 options and close specs overall - seem to be pretty toe to toe, but with only three laptops in their lineup, no desktops and slightly lower entry prices Star Labs seem to be serving a slightly different market, or at least taking their time before they gun for the greats.
