If you are going to tile a countertop in a "wet" area, use 3/4 plywood or MDF, then attach "cement board" and over that apply a coat or two of Kerdi "red guard" or a similar water-proofing agent.
Then tile and grout.
Tile and grout - by themselves - do not waterproof a surface.

I'd avoid MDF completely in a wet area like a bathroom. Particle board as well. The Hardibacker 1/4" backer board on top of exterior grade plywood would be ideal; it holds up extremely well against water.
The ready-to-mix thinset would perform better than the premixed thinset. Small area like the countertop, especially with low usage, the premixed thinset would do okay.
