the only things you need to break a genjutsu is to know you're under one, and being good enough with your chakra to overcome it's control.

Therefore, it doesn't matter what exactly the Genjutsu does. Kotoamatsukami is strong because it's subtle whereas Tsukuyome is strong because it manipulates time and space. Koto makes point 1 hard (figuring it out, but once you know it's easy, see Gokage summit). Tsukuyome makes point 2 hard (powerful torture effect makes focusing hard). Infinite Tsukuyome does both.
