@Polygon:
**It's pretty freakin obvious he is.
He's was the second strongest person under Whitebeard's command, effortlessly stopped a flying slash from the world's strongest swordsman with his face of all things, was able to tango with Aokiji and only lost so quickly because he became distracted, him throwing that iceberg was one of the absolute greatest feats of strength in the manga (only Garp's cannonball even comes close), is implied to be stronger than the likes of Vista who was able to fight with Mihawk of all people on seemingly equal ground for a time etc.
He is without a doubt of the highest tier, along with the Admirals, Garp, Sengoku, the Emperors etc. I mean, sure, there's no way he can beat or fight any of them truly evenly (meaning for an extended period of time) but he can give them all a fair bit of trouble except probably Whitebeard/Roger.**
While I definitely agree with you that Jozu is an Admiral level fighter, I disagree with you that Jozu is stronger than Vista. Vista's feats in the war were more impressive and I believe him to be the stronger of the two. So I'm curious as to what makes you believe that Jozu is stronger of the two.
