I almost did the MDF but went for a door instead. I may go back to the MDF and put some foam insulation or something between it and the 2x4s on my bench to absorb any minor imperfections (I don't see any, but you never know).
Did you use 3/4" MDF or 5/8"? I am trying to find 1" but no one seems to have any locally.
I use 3/4" MDF on my bench. The ceiling tile is dense enough that it stays very flat even with quite a bit of pressure as long as it's not direct. (I get a lot of elbow divot's on the front).
