I almost exclusively do performance and race tires and a lot of tire "flipping" where you dismount a tire and put it back on the same wheel with the former inside on the outside (due to camber wear) and have used lube to dismount a tire one time that I could remember. Out of thousands of tires a year (just did about 100-150 tires at an event this past long weekend). I just don't see the need, but I have good Hunter equipment and am fairly skilled.
That said, using it really wouldn't hurt anything and preferring to use it wouldn't be a failing of skill in my eyes
