Adizero pro 2. More than any shoe out there, legs just feel better the day after. In fact, I use Adizero pro for tempo runs too. For faster stuff, twice a week maximum, I use Vaporfly next %.. i sometimes use endorphin speed for shorter tempo runs around 3 to 5 miles. I don't do any slow runs. I run maybe 3 to 4 days a week with 6 to 7 sessions total, so I am doubling most of those days of running.
