Seems like you didn't read the manga. Sasuke has all Six Paths and Outer Path.
Outerpath is in the moon in another dimension and nowhere in the manga did I see shrina tensei, bansho tenin, ashura lasers, ningendo soul removal, hades soul removal/soul restoration, and endless summoning technique from Sasuke.
He absorbed chakra, used amenotejakra and used chibaku tensei.
Dude when will you learn Pain's feats aren't unique to him ? Obito taught him to use Rinnegan to its full potential and Madara was the one who taught Obito about RInnegan jutsu along with Uchiha jutsu.
Madara did not teach Obito rinnegan jutsu and Obito did not teach pain his techniques. Because.
1) Madara and Obito did not have the rinnegan, nagato did.
So that Six path jutsu that madara taught him were just jutsus that didn't require a rinnegan like Six path jyubi coffin seal and gedo rinne tensei etc.
2) Obito can't use nagato's jutsus and neither did madara. How can you give sasuke feats for something he did not do? Even momoshiki showed different rinnegan techniques
