Yes I went there.
This is probably the hardest to call because they are so similar. I say 6/10 panther because he’s been training all of his life while Bruce started after his parents death. Plus T’Challa has the blessing of a god (different than the panther god since his sister is the new panther) along with his vibranium weaponry and armorBlack Panther clean sweep.
his armour can take a bolt of lightning and he’s not even harmed. See the massive hole in batman’s armour… the actual hole. the bottom of his face. Completely open. That’s his weak point. And black panther would exploit that.
BP’s blades/claws would open bats up like a packet of crisps.
Also Black panther has toys that would make bats weep like a kid who had just seen his parents get gunned down in an alley way by some thug. Teleportation devices, energy shields.. cloaking.. 10 out of 10 for t’challa in my opinion.
