Good looking, easy to install alternatives to drywall
I like MDO plywood (medium density overlay plywood). MDO has a resin paper on one side that you can paint. It comes in 4’ x 8’ x 1/2” thick sheets. (I think it comes thicker too.) 

The only way to “cover” the joints is with a batten. However, the edges are trimmed true and straight, so the edges can be butted together easily. 

BTW, any wall or ceiling in a garage that is adjacent to a habitable space must have a 1-hour fire rated protection on it...like 5/8” gypsum board Type-X or 1/2” gypsum board Type-C on supports spaces no more than 16” on center. But the MDO can be on top of it for the finish
