About hanabi level usefulness im guessing

he is a better version of sage naruto because our sage naruto (hard to say why) still has no breaktroughs even if kurama naruto appeared 6 months ago.

Chase it better than Sage Naturo

He does really good against Akatsuki. Increase Crit and Combo Rate and can cause immobile against them.

It's obviously similar to sage naruto... but I wouldn't say "better" as much as different. One is fire and one is wind and that alone often dictates whether or not you'd want it on a team, but also.... sage gives extra chakra and is quite often on teams that like that sorta thing. Konohamaru gives more options, I guess... But it's certainly not like any team currently wanting Sage would be upgraded by him is all...

His clone is not made of paper tissue, is similar to kushina clone. Without breaktroughs sage naruto clone is just a target for any repulse ninja to own you in one shot.

I don't know what you're talking about, but if repulse ninjas are beating you in "one shot" then it probably doesn't matter what ninjas you're trying to use...

yeah if repulse is one shotting you that means the other guy has over 20k+ bp over you atleast.
