Infinite Tsukuyomi is cast with the raw power of the Rinnegan, with the Sharingan abilities that Rinne Sharingan possesses. Sasuke says it is a Rinnegan cast Genjutsu, Rinne Sharingan literally has the raw power of Rinnegan and the abilities of Sharingan according to manga, databook, and anime. Therefor Tsukuyomi is a lesser version of it since it can only affect one person at a time and in comparison a more limited time while also only being able to be cast by a Sharingan derived Dojutsu(Mangekyo Sharingan)
