Manga: Rinnegan (Hype)
By Feats alone: Sharingan
Rinnegan is Powerful but Sharingan Feats are in its own League. Sharingan counters everything Rinnegan has to offer.
Animal Path- Amaterasu rids of Summonings & prevents them from multiplying.
Asura Path- Susano'o can tank all attacks from Asura Path.
Shirina Tensei- Susano'o can tank Shirina Tensei, a Full Powered Shirina Tensei that destroyed the Leaf Village killed nobody, even Sakura survived it. In fact Naruto's Shadow Clones Tanked it as well.
Bansho Tenin- Susano'o can protect the user from any additional attack heading toward their way while being pulled by Bansho Tenin, Susano'o will be pulled too but they'll still be protected. Susano'o activates at the User's Will.
Rinbo Hengoku- Perfect Susano'o not even needed, Normal Susano'o can Tank it bc unlike the Tailed Beasts Susano'o isn't a living creature thus feeling no Pain.
Chibaku Tensei- Ah... this Powerful Technique. Perfect Susano'o breaks out of it or slashes the Orb that pulls all Objects to it. Destroying it.
Six Paths Technique- This Technique is Overwhelming yet it has a fatal flaw to the Sharingan, all Rinnegan share linked vision meaning that of one gets caught in Genjutsu all Rinnegan get caught in Genjutsu. This includes Summonings as well. Sharingan Genjutsu or Tsukuyomi end it.
Now do you see? The Rinnegan doesn't pose a Threat to any Skilled Sharingan User.
Sharingan may be a stage below Rinnegan yet their Feats specifically alone are in a different League.
Sharingan= Powerful Genjutsu, Powerful Ninjutsu, & an Offensive & Deffensive Sheild. Reads Opponent Movement & Sees Chakra Flow in Individuals & Grants Genjutsu Immunity (Obv not Sound)
Rinnegan= Sheer Brute Ninjutsu, OP Ninjutsu Counter, Potential to Master All 5 Elements, Summonings, & see Chakra.
