The bottom is MUCH better. The top one just kinda looks, i unno, i find blue much easier on the eyes. The top one is very good, but the color blend is harder for my eyes to focus on (helps that i got 4 hrs of sleep lol)
I agree that the text isn't something you can just glance at and know what it says. You actually have to look at it. For me, that's a negative point, but for others, I'm sure it's a good thing. Overall, it's a nice little sig with some cool effects. Not bad at all!
