My parents were human: of course they didn't get everything right, but tbh as a parent who knows I am far from fallible, I don't think I'd find that very reassuring. I could never live up to that, so if they had been perfect, I'd think my dc would resent me for not being that.
So many things they did get right though:
they made all 4 of us feel equally loved- when my mother says that her answer to the question "which of your children do you love the most" is "whichever one I happen to be thinking of at the time"- at 56 I still believe her.
they made us realise that you can be fairly treated without measuring every little treat with a millimetre ruler to ensure nobody is getting anything you're not at any one particular moment
they were ENDLESSLY interested in life- still are, at 87. Interested in big things, like learning a whole new foreign language or saving up for 2 years to take us on the train to somewhere special at the other end of the continent- but equally willing to find interest in a bus ride into town
they were very good at making a joke out of adversity
they genuinely enjoyed spending time with us, even when it made life more exhausting
they had a great respect for privacy
though never afraid to parent, they also (at least my mother) had a great understanding of a child's need for dignity: she knew how to enforce discipline without humiliating
they let us grow up and become independent without having to feel guilty about it- it was a very painless transition
