alt Hacker NewsI'd say Prussa.
I am not going to say they are perfect, but I think they have a good balance of ethics, openness, product quality, innovation, availability and price. By that I mean their are the best in none of them, but I don't think of anything better as a combination.

Buy a bambu; use Orcaslicer
Edit: didn't mean to say "held the industry back"; I would categorize my opinion more along the lines of "were happy to get fat on past offerings" or the like.
