Pros: Attractive and Great Layers..
Cons: Noisey and flighty
I like a breed that is not just a great layer but is kind of a pet as well. Leghorns in my experience are kind of stand offish, very flighty and can be loud. I always keep a few in my flock for their egg production and some of the Browns and Silvers are actually quite beautiful.
P.S. One of the friendliest birds I ever owned was a White Leghorn roo that I rescued from another family member who purchased him as one of those dyed Easter chicks back in 1975. He was dyed green so of course he was named booger. Booger was hand raised in my bedroom until he was old enough to put on the lot with the other birds. He was by far the most intelligent chicken that I ever owned. I could walk out on the patio, sit down and slap my leg and he would fly over the fence run up to me, hop
up on my knee and go to sleep in the sun. Booger...I really miss you buddy! RIP
