With the exception of Rhonda and Rose, I find the wives dull and boring. Robin is so soft spoken she needs subtitles. Both Robin and Paulie seem uncomfortable in front of the cameras. Nonie is not like-able. These ladies just don't have the spark that's made Sister Wives a hit.
I like Nonie a lot more than I did when the show first aired. Paulie & Robyn are very quiet and reserved. Rosie & Rhonda are definitely the most open and outgoing.
They all have good and not-so-good qualities (strictly speaking as a viewer). I'd say that my favorites are Rhonda & Nonie, Paulie & Rosie are just meh, and Robyn is the least interesting as things stand right now. But we've only seen a 1-hr special and one VERY short season, so this is subject to change at any time. :-)
Nonie grew on me....Robin reminds me of the shriveled-up, Mer-people that'd sold their souls to Ursula the sea witch! (Little Mermaid movie...she looks just like them, I swear!)
