The model was hollow and properly oriented.
Was it the ideal orientation? Maybe not, but it was the orientation with the best surface quality i could get.
Currently, the layers are noticably more uneven on my Form1+ than on my FDM printer, making them clearly more visible in prints.
With black resin, i am currently getting marginally better infill on top surfaces than from my FDM printer.

The only edge Form1+ has when looking at the prints side by side is the feature sharpness and thin features.
