Yes the size is the only difference. I was just looking at mine and was pondering the all-important tortilla question and concluded that the quick was probably too small to get the small sized ones flat. Maybe the corn one would fit however. So if you want to be able to do quesadillas without additional prep the flex might be the one you want.
LOL I also agree on the quality of the youtube vids. In fact, it more often than not appear that the less experience with the thing, the more likely people are to post a review.
