+1 on the Dunlops being much harder to mount and dismount. No doubt whatsoever.
I had been running Pirellis and early last year decided to try some GPA Pros. I also have a NoMar. Typically I have zero issues swapping tires.
The hard carcass of the GPA Pro exhibited itself to me in two ways. First, it was just a real PITA to mount. With a Pirelli at room temp, I can often just slap the new tire down and forward on the rim, and get the entire bottom bead into the rim on one swoop. No tools. Then easily get the top bead down into the rim very quickly. And with the Pirelli, I can go ahead and put the valve core in and use a regular air chuck to inflate the tire and set the bead.
With the GPA, I can almost never mount the bottom - or first side - of the tire into the rim in the same way. And even with the NoMar, tools, and leverage, getting the last 20% of that GPA into the rim takes effort. Then, if I put the valve core in before setting the bead, sometimes it just will not set the bead. I have a rubber tipped air chuck that I use to set the bead on those damn GPAs. There is only one tire I've found that was worse - an old BattleAx.
I think if you're looking for front tire wear, I'm not sure there's all that much difference between the Pirelli and the Dunlop. For the rear, discussing longer wear on tires on a new 1000 is like hoping to see a pink unicorn grazing on four leaf clovers. For running A sessions and racing, the Dunlop is a heck of a tire. After the first session, it might wear just a bit better. On an R1 or GSXR1000 that means you might get an extra 5 laps before you destroy that tire. My only reservation on the Dunlop is when you're using that bike to CR on also. I "remembered" last year that it's not smart to CR a Novice session, then just hot pit, yank your shirt off, and go cut some A Group laps. In April at NCBike. The Pirelli warns you that you're being stupid. The Dunlop introduces you to the asphalt.
