We have white backerboard in our office, and it doesn't properly dry erase at all. Instead of just kind of smudges over the entire area of the board eventually just making it a HUGE mess.

At that point we have to clean it off with commercial cleaning spray and paper towels. It works, but is definitely not ideal.

Tileboard is great. Not the highest-quality whiteboard material you'll ever use, but definitely the most cost-efficient and easiest to obtain.
