Agree that "it depends". As with anything, there are junk treeless saddles and there are quality ones. But even a quality treeless saddle still needs to FIT your horse properly. They are not one-size-fits all.
My BO has a custom Bob Marshal treeless that she uses for trail riding (she's very much a recreational rider). But she loves it.
Obviously if you are doing something like roping, you have to have a tree in those cases.
So it depends what kind of riding you do, as well.

It is not enough to know how to ride; one must know how to fall.
