How the finale variant of Kang look and act is almost irrelevant to Kang the Conqueror though, as seen in so many versions of Loki throughout. It's basically like saying you don't like how Alligator Loki looks, when that's not the version we get in Avengers1 movie anyway so point is moot.
The goofy one is dead, we'll probably never see that variant again. What we will be getting will be completely different. If MCU new focus is on Multiverse, then Kang is the next Thanos. This is the biggest reveal ever, it's just so premature that most people won't catch the importance until we see more of the Conqueror in action.
I'm sure they are using the same actor, but expect a completely different performance and costume makeup. I'm guessing the actor is just trying to show his acting range with this goofy version and then comes the serious Conqueror variant, they're basically two completely different personalities. I think this silly version is throwing people off, Marvel didn't hire him because of this version, they got him to play the Conqueror, so we'll see what the real deal is going to be like.
