I'm curious about your experience with the Michelins, like them so far?
Regarding pure grip on a hot summer dry day, they are both very good, can't say I've noticed any differences, as I don't track mine anyway.
What I immediately noticed though, is that when the weather gets a bit colder, under 15C or so (May or September for example) they don't lose their shit like the Pirellis did, and you don't need to drive 10 hours to warm them up. Constant stickiness on the road, without any wheel hoping on acceleration or fighting for grip.
When raining, their behavior is almost as good as when dry, whereas the Pirellis were a joke.
And they look a bit wider, and beefier, which I personally like.
