From a professional perspective, this gives you access to a bunch of different materials that open up all kinds of options for prototyping.
The slight increase in fine detail is just not worth the toxicity imo. Put a 0.2mm nozzle on your FDM printer and you'll get good enough quality. Leave resin to businesses that can set up a proper warehouse with fume extraction and PPE.
You can even prototype your designs at home with FDM and send the final file to a company to do the resin prints.
