The borders and the colors ruin it for me on the first one. The second one is way better. Don't you know that people are going to try to get you to put the worse one in so they have a better chance lol Im being honest though, the second one is better.
Personally, I prefer the first one. The vibrant colours are much more visually appealing. Great depth, blurring where necessary. Only thing I'm not too fond of is the bottom right corner, the large dark space contrasts too much against the rest of it. It demands attention it shouldn't get. That's just my opinion. Take it or leave it.
