Why the hate for stock tires?

I think most here went with the Michelin Road 5 and were happy with them but those of us who chose the Conti Road Attacks know the real story.
Yesterday, I finally busted out my 900 for the first ride of the season. I specifically noted how wonderfully stable the RA3 is in the corners and sweepers.
I doubt I’ll ever change from the Road Attack series moving forward.

My 2023 have the Dunlop Sportmax Roadsport 2 and I really can't complain about their performance. I live in Florida and roads stay hot, so maybe that helps. They have also perform fine in the rain for me. It's even started raining while riding, which is when the road is the most slippery and it handled it fine. And I ride my bike pretty hard. I do hard acceleration coming out of corners, super fast starts and stops and and it handles it well. I normally ride in Road or Sport Mode when I really want the need for speed. 

I see no reason to rush and get new tires. But, when it's time to change, I am thinking of the Pirelli Diablo Rosso IV. Anyone have any experience with that tire and would they recommend them? I plan to stick with OEM size.
