You are right that the best technique is the fastest that gives you the desired cuts. Mind is similar to RedWattle's, but with more knife work.
As for broken chicken bones, it's usually the result of someone being overly aggressive with the bird. Very few chickens raised in the US are treated as delicate flowers to be raised with care. When a worker needs to move 500 birds out of a pen and one is being stubborn, they learn to use those boots. For work I don't have much input into product sources, so I get to deal with it.
My favorite TV cook remains Alton Brown. He teaches the entire process instead of teaching dishes. And his techniques are usually excellent. He had episodes entirely about salt and knives. Julia Child, on the other hand, remains the most lovable but clumsy cook ever to be on TV. When things go well she's good, but when she messes up she's hilarious.
