Bridgestone S21 Vs Pirelli Diablo Rosso III

I know there's a lot of other topics about tires, but I want to know if there's anyone around here that have tried both of these tires on their 1000RR.
If so, what do you have to say about the durability and grip of them?
Which one is better in your opinion for all year/all weather rides?

I'm about to finish my 2nd set of S21s, I think they are the best tires I ever tried, but I'm open to try other tires.

Thanks.

 

Nevermind... Just found out that the S22s are coming out in 2019.

 

I think you'll find most on here are a rap for the Metzeler 7RR. I haven't tried them as I'm still shod with Corsas.

 

I did try the Metzeler M5 before. Liked them, but liked the Dunlop Sportsmart² and the Bridgestone S21 better.

 

If you don't mind a shorter tyre life, Pirelli Super Corsas are magic!

 

So I've heard, but I do mind the short tire life...
I'm getting around 10.000 KMs out of the S21s and that's my goal for every tire I use.
