The best picture quality will typically come from a simple and inexpensive matt white screen IF AND ONLY IF:
1. Your projector has enough light output for the screen size you choose
2. You can completely control the light in the room and make it dark.
3. Your screen surface remains perfectly flat, e.g. doesn't warp or wave over time
A matt white screen has the best off axis viewing, most natural colors and no hotspotting.
The reasons to buy a more expensive screen:
1. You want a motorized screen (convenience + the ability to hide the screen)
2. Tab tensioning, which will keep the screen flat forever.
3. You need more light gain so you get a 1.3 (or higher) gain screen.
4. Your projector has very high light output and can benefit from a high contrast gray screen.
