The Comet and the Cromwell AOE is 2.5(scatter 6.4-12.8)
75mm sherman Armor piercing round AOE is 2(scatter 6.2-12.4)
76mm sherman Armor piercing round AOE is 2(scatter 5-10)
Ez8 AOE is 2(scatter 5.4-10.8)
There's more to scatter than just max scatter distance.
Easy 8 =
5 angle scatter
75mm AP = 7,5 angle scatter
76mm = 7,5 angle scatter
Crom = 7,5 angle scatter
Comet = 5,25 angle scatter (since last patch)
Overall, the Easy 8's gun has average AI along the lines of the Cromwell and Ostheer P4. It isn't amazing like the OKW P4 or godtier like the HE Sherman. Considering its AT performance gives the OKW P4 a run for its money, I'd say that's fair.
