Where did I say that Akaza won? He lost, but it was a two on one. And when Tanjirou cut him, it was with an ability that Akaza didn't know he had, he grew during the fight with a superior technique. I don't get what you are trying to tell me here. All I am saying is that I don't see Akaza losing to Tanjirou one on one with Tanjirou having the STW technique from the beginning. This is a VS thread, to speculate about the outcome of a fight, manga facts are only here to supports our arguments. If you disagree it's fine.
Evidence from the manga disproves your opinion though. Once tanjiro gained access to STV, he was much much quicker than Akazs. & Before he gained access to STV he knicked Akaza's neck with his mirage technique, and was still capable of dodging..Tanjiro doesn't have the stamina seen from other Pillars and less endurance for he had moments of immobility during his fights.
But Tanjiro with STV, can fight Akaza 1 vs 1 like he did briefly before he had such skills...& with STV, he's faster than Akaza so his head is going to fly...Re, read the fight. Tanjiro is def top tier he just lacks in certain areas compared to other Pillars who are already polished.
Also Tokito doesn't have enough feats to be better than Tanjiro even if you give them both STV. Tokito needed rock pillar to disrupt 1st moons attack and he still lost a leg, all to pierce the upper moon, basically that's a bad display if STV, stronger opponent or not. Not enough reasonable doubt to say he can defeat Tanjiro.
Tanjiro damaged Akaza before he got serious injured, and still managed to dodge fatal hits after with some help from giyu, then went on to save giyu and defeat Akaza.
Tokito, marked & unseen technique couldn't do anything to upper moon 1.
