its most likely a step down from the rinnesharingan but a step up from the rinnegan. its not simply the simultaneous use of rinnegan and sharingan in the same eye.if it were,activating it would simply require activating the sharingan ,which should be nothing to someone of sasukes level.but in the gaiden sasuke wouldnt/couldnt activate the tomoe rinnegan because his chakra was low, yet he teleported easily (teleportation would be much more chakra taxing than activating sharingan).its definitely a dojutsu on its own.sasukes tomoe rinnegan is some sort of evolved rinnegan.sort of the missing link between rinnegan and rinnesharingan. not much else could be said about it,its still quite obscure.it seems to be missing a third row of tomoe compared to the rinnesharingan.perhaps like the sharingan over time it can naturally mature into a rinnesharingan.or perhaps not.just speculation. but its definitely something above standard rinnegan.it can counteract and even dispell infinite tsukuyomi so its definitely something special.
