This Sasuke has access to 3 tomoe Sharingan and can only go up to CM1, for some reason I felt like 2 would be too much.

Shinki dog shits all over Sasuke.

While I'm not agreeing or disagreeing do you think that Sasuke's Chidori (with or without CN enhancement) could potentially break through the Iron sand?

Urashiki's blasts couldn't.

Ah, that is true. Urashiki was honestly wack to me so I tend to forget a lot of things he did while in the show. Brought this up though because I remember Boruto's lightning starting to crack through the sand before he cheated, thought that maybe Sasuke could potentially crack through the sand some since his Chidori should be way stronger than that lightning.

Boruto used purple lightning which is significantly stronger than a normal Sharingan. And he doesn't even use the finger thing at that point to amplify it's power.

I don’t really watch the anime. Does shinki have some good feats? He’s featless in the manga.

He does.

Anything that puts him above 3 tomoe Sasuke?
