Not a bad comparison. But once the dog gets his but into the air he can run. Now just imagine what a dog would do with his left front leg being non existant ...
Sometimes I look at these pros and cons discussions like looking at a red haired girl. Some people like it, some don't but all these different preferences produce the variety I appreciate when going to airfields and airshows. Somehow more interesting than distinguishing a fleet of 172s by color scheme and interior fabric.
