I buzzed my head for about 6 months before I started shaving it. There are ups and downs to both. Buzzing is lower maintenance since it doesn't make the dome completely smooth.
I went on a three week vacation, often camping without electricity so I started shaving it, and I couldn't go back after experiencing that a few weeks.
I love how smooth and shiny my head becomes after a nice shave.

In the public perception of the "haired masses" buzzing and shaving would be pretty close. But I like them to think like my nephew does, that I just have no hair sprouting from my head at all, just eyebrows. So I'm a sly man.
