My bike is kick-only. Elimination of wiring and the starter was my reasoning. It fires on the first or second kick each time.
Yes, there is a certain coolness to kicking your bike, especially when it fires right up, just as there is a certain un-coolness when you see someone holding the electric start forever waiting for their bike to come to life.
Part of the appeal, for those of us who love kicking, is the mechanical connection to the machine. It's the same reason I have only ever owned manual transmission cars and trucks. It just makes you that much more integral to the whole process.
If you think kicking is hipster, that's fine. Labeling doesn't offend me. I just don't care. If you love your button, push it. If you love your kicker, kick it.
