"Aizen didn't lie This was what he himself believed."

Aizen has shown instances where what he said doesn't represent the reality of the situation, regardless of what he believed. He believed Ichigo lost his reiatsu, he believed that he would evolve more, he believed that he can use his zanpakuto without the blade etc etc etc.

It's not to discredit the fact that he's extremely smart and calculating scientist. The point is that he can be wrong.

Regardless of that, Arrancar=/=Visoreds. Soul Suicide happens when the original soul get mixed up with hollow's, breaking the boundary between them. This is something that happened to Visoreds and will happen to quincy without hollowfication. Arrancars were originally Hollow who gained shinigami-like power, therefore it's not an apple to apple situation.

"It was never confirmed if Tosen suffered from Soul Suicide." Well, the man exploded like those rukongai peasant Aizen experimented hollowfication on, right when he is weakened from his fight (Only soul of sufficient strength can withstand hollowfication). Aizen didn't appear to do anything, so there is no confirmation that Aizen killed the poor bastard.

Tosen is originally shinigami who turn into hybrid and yes he used resurrection, descorrer, high speed regeneration. Yes he is better in controlling hollow power than Visoreds, but if his explosion is caused by soul suicide, then he's in no way superior to visoreds and for all we know, Aizen could be missing the whole balance of souls thing.
