well his shun shin is basically instant since its faster then the raikage which easily dodged amaterasu....so he basically has unlimited ameno but agreed with the guy saint amen doesn't hurt anyone so basically any technique lol thats like asking which technique does sasuke or naruto have thats stronger then FTG
You can't really scale ameno on a strength scale since it does no damage and has zero D.C. Is it useful? yeah it can be, but compared to some other occular abilities like Kamui or Almighty push, its meh.
Ameno is basically FTG, but without the tags, limited range, and cool down. "meh"
Dude Sasuke already used Ameno+Chidori on Naruto. It didnt work. Not saying it never will. Just saying you fappin it so much when it failed so many times. This ONE tech does not make him stronger than Naruto.
