I don’t know current best options, but last I was looking, the Voron design was where I was leaning. I’d suggest avoiding companies that violate open source licenses.

I used to be a Prusa evangelist, but I don’t forgive them for the MMU2S. Huge amount of people never could get it to work. I’m curious as to the actual percentage working. I couldn’t ever get it to work even with multiple complete rebuilds. That product should have been recalled or a free fix offered. Years later they released a new version that supposedly fixed the issues and you still had to pay to upgrade to it. Discounted if they had a support record for you. If not, full price.

From time to time I see a new Prusa printer and think “that looks good, I should buy it”, and then remember the insane amount of time I wasted trying to get the MMU2S to work. Never buying Prusa again until they provide me the working MMU I paid for at no additional cost. As there’s basically zero chance of that, my boycott continues and I suggest not supporting a company that fucked over their customers with an expensive poorly designed product that they then want them to pay to fix.
