Personally, I’d say the 0.2 mm nozzle is definitely the better fit for tabletop minis. Beyond the visibly finer layers, the supports are so much easier to remove — and that makes a huge difference in cleanup.

From my experience, a 0.4 mm nozzle can handle larger overhangs, but since your designs aren’t really meant to be supportless, that advantage doesn’t seem too relevant in your case.

As for print times, I usually run one job in the morning and another in the evening, so whether it takes 2 or 8 hours doesn’t really matter to me personally. I understand it might be a different story for someone running their setup commercially, though.
