From your list, I have RIR, the red sex link and used to have a WCBP. I've been very happy with the RIR and the RSL, both for egg production and personality. The WCBP was a freebie from the hatchery. He was an adorable chick but as soon as those top knot feather started coming in, he was harassed constantly so I had to separate him from the dual-purpose girls. We lost him around 3 months of age but he never would have been happy with the other birds and I was going to have to make a choice to re-home him or get him some other Polish for companions.
This is Taylor, my RIR girl and DH's favorite: (her chick pic is below this one)
This is Scotty, one of my RSL's and my lap girl: (can't find her baby pic, so showing you her flock mate Sue)
