in warm and dry environment both the pirelli and michelin will be excellent, where the latter stands out is in longer tread life and supreior cold/wet performance.
Anecdotally the pirelli pz4 hasn't done a great job so far with Toronto in the 45-55F range and frequently rainy. I rmb going up an uphill on-ramp in 4th and rear was spinning lol... But the few days we had that was very warm and very sunny, the grip was impeccable and I could echo the broad reviewer sentiment that its almost AWD-like.
C&D did a test comparing this class of tires a while ago and have similar conclusions
