As a former Mac user, I'm really happy with my System76 linux laptops. The only tradeoff is the terrible built-in speakers. My Lemur is lighter and has better battery life than my Macbook Air and has been bulletproof despite my ill treatment. Each of my Macs, however, have had various hardware failures or the famous keyboard recall on the horrible touchbar Macbook Pro. I also prefer matte screens to glossy, so that's a win for me, but ymmv.
* Battery life is a lie, especially since it drains almost as much battery closed as it does open.

Overall, I think I am probably going to switch back to a macbook after this, not being able to go a day without charging and your laptop always being on low battery is a bit anxiety inducing.
