Corn ones do make the best enchiladas. They do not, however, make good burritos.
You can make your own and press/roll/pat them out a bit bigger.
The brown rice tortillas make good quesadillas (you have to heat them on a hot griddle to make them pliable), but don't roll. I've heard good things about some other brands of GF tortillas, but most of them contain my allergens, so they're a no-go here.
