Well true but look, he was sick before he had his chance with sasuke, then he had to choose a random body, and almost immediately after he stated his body was failing because it couldn't handle it, so basically he got sick very quickly and basically only had a few weeks maybe a month at full strength, in which case we never saw him in a fight
and still he was scared about the sharingan and he wanted it so badly
Orochimaru failed at itachi because of the genjutsu as he did at sasuke
