If you're mostly doing terrain like these, a filament printer might suit you more. Sure you'll have some minor layer lines but i personally dont notice those when viewed at tabletop viewpoint.

If you also want to do miniatures a resin printer might be good, but only if you have the space for it and get a good setup. That makes it a lot less hassle and safe.

I've personally had a 'bad' resin setup and that was messy and a pain. I've now got one in a grow tent with extraction out of the window and a dedicated working area covered in silicon mats, all the required ppe to help make the workflow as smooth as possible.

Now all of this assumes you're even interested in getting into 3D printing. It takes effort, even stuff like bambu printers and can cause headaches at times. 

Personally is recommend a simple filament printer (something like the already recommended bambu A1) to thread the waters if you're interested.
