Blindfold Merz stronger than Drained NJ5 Sasuke (whose statement is also likely taking his PS into consideration) who is stronger than Drained Shin fight Sasuke because that NJ5 Sasuke could still use Perfect Susanoo whereas the latter couldn't, and from that, stronger than Shin Uchiha
Prime Merz stronger than FP NJ5 Sasuke, who is stronger than Momoshiki fight FP Sasuke, but may be weaker than Jigen fight Sasuke
Rescued Nanashi scales higher than NJ5 Base Boruto, but below the 3 Warring Era Uchiha that guarded her
Boruto fight MS Suppressed Nanashi scales somewhat below NJ5 Base Boruto but that is hard to connect to other main Uchiha characters
Revived normal FP Nanashi is stated by herself to be able to use ET as long as she has full chakra amount, but is very hard to connect to other main Uchiha characters in terms of combat and stats scaling
Boruto fight MS Controlled Nanashi scales massively above NJ5 Base Boruto, but quite hard to scale her properly in 1v1 against other main Uchiha characters (this Nanashi's fireball did take Drained Naruto's giant chakra arm a bit of time to destroy)
Merz fight Nanashi could give Boruto enough chakra to pull off insane feats and fight against Prime Merz along with Drained Naruto and Sasuke, but also quite hard to scale her to other Uchihas
