Sharingan vs Byakugan vs Rin'negan
Byakugan = More towards supporting the coolness of Sharingan for it gives Sharingan's origin.
Rinnegan = More towards people who are bored of Sharingan so in turn, it is a compensation from Mr. Kishi himself.
Sharingan = Cool at first, but it is now severely overrated.
I'm still liking the Sharingan the best. Although I'm sure the Rennigan will prove to be really cool when kishi shows it's full power.
So what's the result? It is still, ALL ABOUT THE SHARINGAN.
Sad but true.
