Qualifier: My experience is with 2011 and 2014 Ninja 1000s, commuting/sport touring mainly in the north west corner of the US & over the border in Canada. All reviews are with a /55 profile rear.
Huge Pilot Road fan from all the way back to the Road 1s. I was going for mileage and wet performance and they delivered. Up until Road 4s it was all good. Mileage went up with every revision and rain performance just got better and better. With road 5s I ended up with weird feathering on the front tire. I didn't really feel it but I ended up changing out the tires based on front tire wear. I then went to a Road 5 rear & Road 4 front. There was also forum suggestions that the feathering could be fixed with suspension changes. I never got around to trying that.
At one point, I tried a Road 4 GT thinking maybe better mileage at the back end. That was true but it came at a cost. That tire is definitely made for HEAVY bikes. On the Ninja it feels like it's made of concrete. All the little road nubbles I never use to feel went right to my spine. I did not go with the GT tire again.
Enter Dunlop's super unbelievable cheap (w/ $60 rebate) Roadsmart IIIs. Gave them a try and never looked back. (2014 N1k) This tire made the Ninja handle better. Even "more" neutral feeling and slightly easier turn-in than the PRs. Even better, they feel "softer" and absorb even more of the little road nubbles making for a more relaxing ride. But...about 8k into my first set I noticed the front wasn't wearing even. There were slight indent on either side of the center of the tread. The tire guys said it's a dual compound tire and as it flattens out on the road, the center wears less than the softer side compounds. He suggested running 38# in the front. I just started that when me and the blue Ninja were swept off the road by an unobservant trucker.
I haven't picked up my 2018 Ninja yet but I will be running Roadsmart IIIs on it when I do.
