sorry i didn't mean to confuse :) unfortunately now Aizen has all his new forms (currently somewhere between SS3!!) and it makes it awkard to relate to which stage of power i'm trying to refer to.

here's how i see it working

Aizen pre hogyoku fusion - people like Isshin, Uruhara, Yoruichi, Yamamoto, Tessai and other very specialized high powered characters could have taken him. which is why he didn't bother just kicking everyones head in on top of Sogyoku Hill at the end of the SS arc.

Aizenpod - the combined efforts of a fresh and pre prepared Isshin, Uruhara and Yoruichi could only just about keep up with him, same would probably go for any other particularly powerful very fast character - i expect Byakuya would have been pretty useful to have around.

Full Form Aizen - has shown that nothing and noone can stand up to him.

So when i said about Tessai being better i was talking about Aizen pre fusion/subdjucation.
