Hey, I was just helping you out; you said "i wonder if there are anymore abilities the Rinne-Sharingan can do" so I chimed in with what info we have so far.
And that fight would be interesting. I think you would need to level the playing field with chakra levels for it to be a fair comparison. If two people with equally high chakra fought -- one person wielding the Rinnegan and one wielding the Rinne-Sharingan -- and they mainly fought using the powers provided by the two dojutsu, I think the one with the Rinnegan would win.
Also, the only user of the Rinne-Sharingan we've seen actually use it's powers was Kaguya, and even she got tired out by spamming it. Even if a Rinnegan user wouldn't be able to overpower a Rinne-Sharingan user if they had equal chakra, the Rinnegan user could win by just outlasting the Rinne-Sharingan user. Unless the Rinne-Sharingan user automatically has Six Paths chakra. So many details need to be fleshed out, but it would be a cool versus match to suggest.
Pretty sure the Rinne Sharingan doesn't have abilities of the Rinnegan, though it does have the abilities of the base Sharingan as well as the Amenominaka (Kaguya's dimension hopping thing) and the ability to cast Infinite Tsukuyomi. Makes it less appealing to me than the Rinnegan, tbh.
Rinnegan for sure. At best, I get Limbo clones to do things for me. At worst, I get to be lazy and drag my phone to my hand with Bansho Tennin... oh, and the ability to sprout extra, customized limbs is handy, if you catch my drift.
Nagato and Itachi don't have a 0% chance, but... Even if Nagato managed to siphon off enough of Madara's chakra to heal himself and Itachi had the Totsuka blade at the ready, Madara wins 99/100 times.
