Whilst i agree that sasuke is indeed stronger than Minato you are wrong about what bee said.
Bee NEVER fought Minato. The countless duels was between A and Minato and the one we saw was no exception. Bee wasn't fighting Minato, Ay was. He just decided to intervene because he felt his bro was under threat.
If bee fought Minato why would he say apart from Ai, sasuke is the second person to deflectnumber 8 [

]. That alone should state that Bee has never fought Minato.
If bee did fight Minato and he stated that nobody apart from his bro has evaded it, that means he actually hit minato and minato doesn't have the durability feats to survive that attack. Secondly v1 bee though fast, isnt as fast as his bro, so you'd expect minato with hirashin to evade it
