I think they're a little edgy :lol.
Sasuke has Rokudo chakra = check.
Sasuke has Rinnegan(more closer to Kaguya's RS) = check.
OT: Sasuke has Hogaromo level ability = check.
Rinnegan grants the user access to the 6 paths = check.
People are right he's not Hogaromo, he's the new sage of 6 paths. I say this while confirming I'm not a Sasuke fan. Hogaromo was known as the sage of 6 paths for having the rinnegan( granter of 6 paths) not being the Jyubi Jin as far as I'm aware.
He was not known as SO6P for rinnegan. He was known as SO6P for defeating the juubi as well as for creating and spreading ninshuu.
On another note, he also had rikudou senjutsu which could have contributed to the SO6P moniker. After all, someone in the NV who masters senjutsu of a certain type is called a sage of whatever that type is.
Case in point: Jiraiya learned toad SM and ultimately earned the moniker of the toad sage.
Well, Hagoromo learned six paths senjutsu, and as such could be called a six paths sage, or in other words, the sage of the six paths.
Even so though, I'm pretty sure it has more to do with him beating the juubi and spreading ninshuu.
Anyway, the rinnegan isn't the only thing that grants one the power of the six paths. The juubi grants it. Chakara fruit can grant it. Rikudou senjutsu grants it. Technically even the tenseigan grants it (remember, Hamura's chakara is also six paths chakara).
Anyway, the title of SO6P has more so to do with the ingredients you have rather than your skill/power.
Sasuke having Hagoromo level ability is just a testament to Sasuke's skill, but you don't become the new SO6P because of skill. You need the components (the eyes, the body, the rikudou senjutsu, the bijuu power).
Think about it like this:
Beerus has skill/power that far exceeds a Super Saiyan. However, that doesn't make Beerus a Super Saiyan, or even a regular Saiyan for that matter. Why? It's because he lacks the Saiyan genetics that makes a Saiyan a Saiyan. In other words, he lacks the ingredients (the tail, the S cells, etc...).
Just because his skill and power exceed that of a Saiyan doesn't make him a Saiyan.
In the same way, just because Sasuke's skill (in one area mind you) is on par with SO6P, doesn't actually make him the SO6P.
Long story short: It's not about skill. It's about the specific ingredients.
