I'd say my "perfect oc" would be Grimms! I made him on a whim when I wanted an avatar for amino, but since then he's been my most precious guy :)

he's both complex and simple! he has many small details, but half of them (mainly ones for his face) are optional. I think it helps that he's from a special interest fandom, because I find him to be one of the easiest ocs to draw :)
