Just to add to this post, the resin isn't great to handle, but crucially for the end user, you need to post process the part quite a bit before its "usable"

The part needs to be washed, and then stuck in a UV bath to do a final curing.

Having said that, you get higher precision parts and can print in optically transparent materials.

Optically transparent materials is a very good point, and it hints at something else that I should have included in my roundup, which is that resin prints are much, much closer to isotropic than FDM prints. There are layer lines in resin prints but they are hard to see, and the nature of layer bonding at exposure means there are few layer-to-layer weaknesses.
