I think genjutsu is a more strategic tool than an offensive one. By nature as an illusion, it doesn't have as much action potential. It certainly can be used to shown many things, but the effects in the end aren't that many. It served as a great exposition tool for infodump though. In my opinion, the best genjutsu isn't necessarily the most powerful or debilitating, like Tsukuyomi, but the ones that most succeed in tricking and misdirecting your opponent. The greatest example of that I can think of is when Sasuke made Danzo believe he still had a Sharingan to sacrifice for Izanagi.
