Resin is higher quality and more detailed than FDM, but there are a lot of drawbacks right now. It really depends on what you want to print.
My FDM printer sits in my office and the footprint is tiny. I mainly use a smaller FDM printer fwiw. I can print and design without much effort at all. I mainly print stuff for around the house and boardgames. FDM spools are cheap and the options are endless now. Glow in the dark, PETG, ABS, Wood filled, magnetic. coffee. Yes, the wood spools are sandable and stainable. smell terrific as well. There are now multifilament printers for doing colors. You can also get massive print areas with FDM. Full size vases and helmets etc.
Resin. You will want a basement, workshop, or dedicated room for it. The fumes are toxic and unpleasant. You need a table you don't care about, because it will get fucked up by the resin and the cleanup. Everyone says they wont be messy, but ultimately you will get toxic goo to spill. The Print area is smaller and takes longer than FDM. You must cleanup the print with a wash station. Trimming the tree supports can take a while. There's maintenance with the build surface and resin, but I would say there is less mechanical maintenance than an FDM. Certainly less that you can work on. It's far more expensive for the resin as well. Getting detailed prints to work in resin can take several attempts. Tree supports are rather complex, and it's a bit of an art to learn where to place them with Resin printers. Not really difficult, but it's certainly not automated.
The upfront cost is about the same for both for a mid tier instrument. If you are looking to get into the hobby of 3dprinting, then I would still recommend FDM. Go with resin if you are looking to professionally prototype parts for review. Resin also if you have detailed recreations in mind. Miniature gaming figures dont work on FDM, they look amazing on resin. Just don't plan to use Resin for production scale printing. There are things you just can't print in FDM than you can with Resin.
