Teq:
I liked that you tried to change your flow a bit throughout your two verses. It makes 'em engaging, makes 'em fresh. However, I feel as if your first verse was pretty irrelevant to Spawn. I could be wrong, but I think the "Comic Book nerd" thing is the only thing related to him. I suppose it's to be expected when someone goes first, but I feel you could've made it much more personal, for sure. Your second verse was an improvement in that regard (you mentioned his power outage, how it was convenient. That he threw the N-word, talked about guns. And brought up his breathing issue). That's the kind of stuff I expect to hear in battles. Stay away from the generic 'you suck/I'll beat you down' and 'you like d---' lines, and keep it personal. That's my thought on that.
Spawn:
Probably because he had something to work with, Spawn was able to keep his first verse relevant. Saying Teq talks about d---, Milkdud would be an improvement, Spawn'd be more real than you if he went LARPing. I do wanna add, though, that you made it seem like Teq ignored Flex's lines in their battle awhile back. It was 32-32, blind, though, so Teq wouldn't be able to reply to it even if he wanted to. Not a big deal at all, but just thought I'd bring it up. Also didn't get the Big Pun bite (although I'm not the biggest Pun fan, so there's that). Still, good lines in both verses. Also, I think your flow in the first verse was fine. Not sure what people are finding wrong with it.
Yadda, yadda, yadda. My vote goes to Spawn.
