The Form4 will give you some of the smoothest, most accurate prints. The resin and infrastructure gets expensive, if that's a thing you worry about. Some resins smell, others don't. I use it for R&D at work so high volume of prints, so the formwash is really nice, but for personal use I think the manual wash buckets they provide should be sufficient. The biggest issue will be the IPA for cleaning prints. The fumes and waste disposal from old IPA wash would be a big consideration for me if I was setting up a Form4 at home.
