I hope people don't just use various term (like "sneak attack") according to their own definition.
When Sanji kicks Queen's head and swing it around deflecting Pero's arrows, that is a sneak attack. Because Queen doesn't know that Sanji is fighting him.
When Queen starts 1vs1 against Sanji, it means he knows clearly who the opponent is. You can't label Queen's slow speed/reaction times/not able to find Sanji as sneak attacks.
We can spin everything according to our narrative, but be aware that it is not always the truth.
