From a male perspective, and from someone who has tried 2 European Wax Center locations, I must say that the quality of the wax is poor and the people who do the waxing seem to be pretty new at it. Both times that I used European Wax Center, I got red pimples all over my chest and back. This didn't happen when I went to a wax specialist that used higher quality wax and who didn't rush through the whole thing by using larger wax areas.
The wax specialist told me she had never waxed a dude's front and back...that was a bad sign. She didn't even rub or apply pressure after ripping the strips off! And the person at the front of European Wax Center always tries to convince you to buy the overpriced liquids/gels that they have. I fell for it the first time and ran out of the entire bottle in 2 days. For women who wax small, less painful sections, I'm sure the liquids work, but for guys waxing larger areas, it doesn't last long.
For women who are waxing smaller areas, then maybe EWC is a good option for you. But for guys who need serious manscaping, I wouldn't recommend it. I went to a place that took more time and used higher quality soy-based wax and smaller strips for the same price. I only considered EWC a 2nd time after my crummy experience at another location last year because it's in the heart of Squirrel Hill--super close by.
