The choice between corn and flour tortillas really depends on your personal preference. If you like a more traditional Mexican-style quesadilla, then corn tortillas are a great choice. They have a slightly nutty flavor and are more resilient, so they hold up well to the heat and the weight of the filling. Plus, they're gluten-free if that's something you're looking for. If you prefer a softer and more pliable tortilla that can wrap around your filling more easily, then flour tortillas are the way to go. They also have a milder flavor, which can be nice if you want your toppings to be the star of the show.
