Which housewife out of ALL the franchises do you think is the most intelligent?

This can be housewives that are currently on the show or past housewives. I've been rewatching past seasons of all the franchises and I'm curious to hear your opinions!

Edit: forgot to mention what mine would be but I do love a housewife who can articulate herself well. I love Carole and Boz this new season of Beverly Hills is my GIRL. I loved Nicole from Miami too and I hope she comes back
