On stores that run both
Only 3 of the stores we checked load both, too few for a fair head-to-head. Stores often pick one of the two.
Each band is an app's typical processing time across the stores it was measured on. Those stores differ from app to app. That makes the result on stores that run both the fairer test. Apps found on fewer than 20 stores aren't listed yet. The list grows as more stores are checked.
