The poll doesn't really answer what you would use if you had the choice. And such a poll would have bias or very few votes since I doubt many people have used MS Paint, Paint Shop Pro, and Photoshop, as well as additional programs, extensively for making tilesets.

Anyway, my arguments in the other thread were not to say that MS Paint can't be used to make good tilesets, but to say other programs (particularly PSP) can make creating tilesets much, much easier if you know what you're doing.
