Well I have many breeds
I have Brown Coturnix-- I like these a lot, they are very friendly too.
I raise Mountain Quail too, these guys are my least favorite, they are hard to raise, they die easy and are too expensive, So i will be selling them when the weather becomes cooler.
I have Button quail, these are nice and cute little birds, but are too flighty, and the males are brutal to eachother during the breeding season.
I raise Orange bobs, White bobs, Northern bobs, Mexican Speckled, Snowflakes, Smokeys, and Tennessee Reds, they are all nice birds if you keep them in small enough cages so they get used to you and if you don't make a sudden movement, then they stay calm. I would like these more if they weren't so noisy.
I have Gambel's and Blue scales also, these seem flighty and you can never tame them. The Gambel's can be really mean towards each other, so when you introduce new birds do it in the winter months when birds make natural coveys.
But My favorite would be the valleys, these little guys seem to lay more eggs than poop in the spring time, lol! They are flighty and you can't really calm them down, but they are really pretty and easy to raise, so these are my favorites. They also get along with other breeds really well
So here is my list
Valleys
Coturnix
Bobwhites
Buttons
Gambels/Blue scales
