So many sentences use τέλειος. I don't think we say things are perfect as much in English. Maybe 'great' should be suggested more often.

We have "perfect" and "great" "sense of humor". And yes, I think "excellent" would also fit. Have you made a Report? Please do that when your sentence is not accepted.
