I'm done.
You're just too dense and completely clueless on units roles and stats.
Ironic in that you think comparing a premium med/pseudo heavy hunter is a good comparison against an anti heavy medium tank destroyer. They both have good penetration. They're primary roles are killing tanks. Other similarities end there.
I know the stats. In fact regarding the E8, its anti tank/anti infantry performance has been the subject of a lot of debate here and it has largely been concluded that while the E8 is a great anti tank option, its overshadowed by the Jackson while its anti infantry abilities are lacking. You know, the poor aoe combined with low rate of fire?
As for roles, you may as well say the M8 and Ostwind are comparable if you are just taking the anti tank or anti infantry roles as what determines comparability between units.
The comet is literally the closest analog in terms of stats and in terms of role overlap to the panther. Sure the panther hunts tanks better, no question. Comet is the next best thing. It just so happens the comet is also decent at anti infantry.
You are just digging in your heels here to defend your faulty logic.
Firefly a better comparison to panther then the comet? What are you going to argue next, that the centaur should be compared against the brumbar just because they both happen to be anti infantry specialized?
