Complexity, evolved-ness, and adaptability are three different things. Evolved-ness refers to amount of time that something has been evolving. Adaptability refers to the ability of an organism or a species to survive in a new environment. Complexity, like you said, more or less corresponds to genome size. Rice is actually genetically more complex than humans are, so assuming humans and rice have a common ancestor, we are equally evolved but not equally complex. It is debatable whether or not rice is more adaptable than humans.
