You do make a good point.
However We know that Lariat os only used with the aide of a chakra cloak which enhances the body. Six Paths Sasuke is not fair because he is augmented by Hagaromo. All his moves are powered up with no thanks to himself.
When I compare these moves I dont count Sux Paths. With Six Paths Kakashi pawned Kaguya the strongest being.
We've seen Sasukes chidori go up against Raikages armor so yes Lariat would win.
With Killer Bee its different because we dont know how durable the cloak is.
So you're deliberately leavong out Six Paths Chakra because it would go against your belief? I mean I'm all for wanting Raikage to win but if the only way Raikage can win is by you taking out SP chakra then I think that's pretty disrespectful to the Raikage and says a lot. That's like when multiple Sasuke fans say that Naruto loses to Sasuke when he doesn't have Kurama and Sasuke still has rinnegan.
I am using both Sasuke and Raikage at their strongest. But you're using a Sasuke that hasn't even mastered Susano against someone who has mastered lariat for years. Lightning armor isn't natyrally apart of the lariat technique. Again as shown with Bee one can use it without it.
Again it's entirely bias to pit lightning armor enhanced raikage using lariat against Sasuke who isn't at his prime.
Another fallacy here is that again if two Raikage one used chidori and one used lariat someone would have to be bias to think lariat still wins. On that note you basucally made the assumption that a chidori wielding Raikage at that time would be weaker than chidori woelding Sasuke at the time? How does that work?
Sasuke keeps his SP power handoit or not it's still his if thus was a topic on who has the strongest mode bar juubi jins people would say RSM Naruto even though he got his power up from hagoromo. On that note I can say that Raikage's chakra isn't really his and that it originally all nelonged to Kaguya the first being with chakra if you pit Raikage against kaguya are you going to say raikage wins because you don't count kaguya because her power is no thanks to her but the chakra fruit she ate therefore Raikage wins against Kaguya?
I like Raikage but I'm not going to bring another character down and keep Raikage at his best just so Raikage can win or look good. I never do that with any character which is why I am not ashamed to say Narito beats Sasuke in certain situations.
It's true we don't know the extent of bee's armor but it's not lightning armor. And lightning armor is by raikage and naturally lightning repells lightning the stronger one. If you wanted something truly fair you'd have to pit Adult Sasuke without SP chakra against raikage the former which doesn't exist with good reason.
