Expecting a better performance and expecting a one-shot are two different things. I am not singing a different tune. I always maintained that Kaido is strong enough to answer gears whether it is G4 or G5. The argument isn't about Kaido performing better; it's about Luffy doing better than his previous power-ups.
They aren't half as bad as you're making them out to be. At this point, you're basically attacking them for seeing things differently.
G5 did improve Luffy performance.
He can catch thunders and attack with it. He increased his durability, his physical stats had been increased. He can go G4 without haki, and I think there is still lot to come from G5. So far, has yet to properly control his awakening. G5 is not like G4. The last panel in this chapter was the first time Luffy properly used offensive G5 attack. A first as big as Onigaishima island. And I don't think this is the final punch.
Having different opinion is different from having bias. You like X, I like Y, that means we have different opinions or we look differently. Some like seinen, some like comedy. So again it is different taste.
Let us come to one piece, if I say Sanji >>> Zoro, that means I can't read properly/or I am biased or I see things in a different way?
In conclusion, biased view =/= different view.
