I've not used the piston style, but I suspect just as the wedge is allegedly a little more accurate, it is also probably more fussy with tighter tolerances making the cheaper QCTPs more prone to binding. I have a Little Machine Shop OXA wedge type for my Sherline, it required just a little bit of adjustment in fit at first but now the tool holders go on smoothly every time.
I've also got a larger wedge type BXA Phase II on my 10x24" Powermatic and it required the prior owner to take a little off the wedge to work at all. Even with that modification it will still occasionally bind when changing tool holders requiring some jiggling of the handle and tool holder. I very much doubt that is an issue with a real Aloris or Dorian.
I agree with Dabbler on the need for a QCTP, they are very much a nice to have, not a need to have item. I used the standard* rocker tool posts on my Sherline for a couple of years before buying a QCTP. I still find there are times that the standard tool posts are useful, and having used both now I find that I was not in anyway handicapped without one. It simply makes tool changes easier.
*Sherline's rocker tool posts are sort of a cross between a lantern and the type found on many mini-lathes.
