I like both a lot but Tate had the skill and athleticism advantage while Brewer had size and heart. One thing about Brewer is he was kind of Chiney. I think Tate takes it.
The last part of your comment is why i think Tate wins it his chin was considerably better than Brewer's. Tate is one of the few people to go 12 rounds with Julian Jackson. And he traded punches with Jackson aswell he didn't run and he gave him a very tough fight infact it was quite close on my card. Without looking it up i believe the only real stoppage Tate had was vs a prime RJJ who let's be real was a freak at that time with his speed/power and his H2H ability is crazy. Tate by stoppage between 7-9 rounds in a very entertaining fight both men could be involved in some wild slugfests so expect fireworks in this one.
