Kind of hard to tell from the pics you posted since they are from very different angles, but I add my vote to the smooth look. Looks younger, and sharper. You've got the classic domed head that looks good shaved.
I am not biased toward the smooth. I use a trimmer designed for professional fades with no guard every other day. Keeps my hair around 1mm long. I find that to be the most comfortable for me, and the quickest and easiest. Because my remaining hair is so thick it looks about the same shadow-wise if it is shaved smooth or at 1mm. I envy guys who can shave without a heavy shadow.
