Website Navigation Bars

Currently redesigning the website of a tiny dev company a friend of mine and me are running (I'm the UI/web guy while he does the all the obj-c coding).

I'm stuck between these two navbar designs, an indented “behind the rest” concept and a standard extruded button bar version. I think I like the idea of the indented one better, but think that the bottom one has a little more “pop”. Which one would you choose?
