Kyoshin VS Aramusha

Hey guys.

I have played for honor about 5 or 6 years ago. I did play Aramusha fore just a little bit. Since I came back, there is also Kyoshin. Can someone who is better versed in the game explain how is Kyoshin just not a better Aramusha? They basically have the same things with Kyoshing seemingly beeing bettere - better all guard, instant unblockable, undodgeable, lasting longer in all guard, having more bashes etc. I understand Aramusha has infinite combo, but who cares? Not like infinite is usable in any level of gameplay above bots. The way I see it, it's copy paste and make better. Am I wrong and why?
