The stylists are always lovely people, but sadly I have often ended up disappointed with the cut (nothing fancy). I would find it too embarrasing to go back, so I just put up with it and wait for it to grow out.
The prices have gone up quite a bit, but that's understandable, and the price is still much lower than the more fancy salons.
Being able to turn up at our own convenience and wait a while is always good, depending on how busy the salon is, of course.
All in all I will still use Supercuts, for convenience and price, but accept that the cut I have may not always be quite right.
