for Flat pieces with a surface texture like the brick wall you showed PLA is great. I have used a PLA MakerBot Cupcake 3D printer.
I don't do a lot of large flat pieces on my FormLabs 2, I use my GlowForge 45W laser cutter instead which is a lot faster.
For small quick resin prints or test prints I use an EleGoo Mars which is very inexpensive to use.
As to strength make a 2" x 2" x 2"- 1/16" inch thick hollow box with your PLA printer; then put the bottom in a vise and see how easy it is to pull up and break apart along the horizontal layer the top part.
A break apart along print layers wont happen with a 3D FL2 resin printer
