Comparing only one aspect is how bad breeding programs get started. You need to look at the whole animal. When people look at one trait and breed for it they end up with animals that are far from what the standard should be and often develop health problems. Personally I also put coat/feather color last even if the standard calls for a specific color. It's the least important part to have a healthy, functional animal that passes on good genetics. Then again I don't show much aside from performance classes which don't really exist for chickens because of how many people breed just for looks and create poor quality animals.
