Hash has definitely created a more aesthetically pleasing logo and has created a better style guide, and clearly is the better designer. I think the coin looks mature and its a quality design. The only problem is the logo is no easily legible. the chain is easy to spot and recognize, but if u arent familiar with it you wouldnt know it says NXT. it just looks like a chain.
WIthout writing NXT generation of cryptocurrency under it its illegible. could be a problem.
the other logo is easy to read etc but it looks a bit more amateurish compared to Hash's/ Perhaps he could improve it by making another alternative logo in the same style that is clearly legible or at least has a legible N if not NXT.
