Sage Mode>KCM

[Gerkak]

8Th gate>Bm>7th gate>Sm=6th gate

8th gate only gives you the power of a kage and you die afterwards, while BM>>>>kage and isn't fatal.

KCM is overall better IMO. Doesn't require staying still to gather chakra, Those chakra arms that can spam multiple versions of Rasengan, Flying Thunder God is accessable to Naruto in this state.

If we are talking strength and Taijutsu then SM is stronger, but I think it ends there.

Well if naruto had the ability to merge with ma and pa, who are very proficient in other elements and genjutsu, then Naruto's sm would be in a league of its own...

But as of now with the limited sm..

BM>KCM>SM

No it gives power greater than any kage learn your facts

according to you BM>>>>>Hashirama he is a kage

 

[Sennin of Logic]

KCM is far better than Sage Mode in every category besides sensing.

SM has far better strength, reflexes, and taijutsu over all in addition to sensing.

See them apart from each other. First of, SM is Naruto's feat alone. It bring an entire different type of chakra and in this you should see it qualities. The chakra is more dense and powerful.

However, KCM and BM rely on Kurama... this brings out the quantities. Whenever there is a need of a lot(read overkill) then these modes are better. Much better.
