The logos were so similar that when I opened them in tabs, I began to question whether the original post was a joke. I'm still not really sure what's going on.
Kim got rid of the 3D, made the colors more bold, and removed some of the outlines. The changes also had the effect of making the word "AdBrite" appear larger, even though (in this comparison) the images are the same size.
Subtle, but was meaningful to me. Because (a) I liked his version better, and (b) In all my years entrepreneuring, it's the first time someone -- unsolicited -- offered to improve my logo for free.
I don't like either of them, but if I had to choose one I'd pick the 3D one, it looks smoother and the red in non-3D version is really emotionally negative, like it's the kind of red that makes you angry or scared.
Are you sure you clicked both of them? The first had a really harsh and strong border and looked almost 3D, but in a cheap and bad way. The second is much more subdued and 2D.
Both of them would look very dated today but this was in the early 2000's.
Kim's version is definitely better. It's much simpler and doesn't rely on superfluous visual effects. The shape of the logo comes through, and it uses fewer colors -- both of which make it much more recognizable.
