I've used and own both, and prefer the Pat's Easy Change system, especially with telescoping stabilizers. With the telescoping stabilizers and implements that are the same pin width, i never have to use the spreader bar that comes with the Pat's system.
The other advantage to Pat's, is space. the box frame QH's take up alot of valuable space when trying to hookup (wrestle with) a PTO shaft.
Both will add a few inches to the overall picture, so this needs to be accounted for with PTO shafts.
A negative to Pat's system in my experience, is the top link. Because your lower links get extended and the top doesn't, you lose length adjustment, which takes away angles on things like box scrapers. I changed my top link to a longer CAT2 top link with bushings that i staked in place, so i could still have aggressive angling with my box blade.
