I'm not absolutely sure yet. The old one was attractive and caught my eye more, or maybe I was just used to it. I think they have tweaked the new layout to make it look pretty cool, though. It looks clean and professional. They did make the voting buttons more noticeable than the earlier draft of the new format.
I don't like how the "link to this page" is almost hidden at the bottom and some of the sharing buttons (like Stumbleupon, Redgage) are gone. I miss seeing the score of the hub (is that still one some of them?), but I don't know that it's important.
Something that I DO like about he new format are the larger notices of more hubs at the bottom. There are the two from the author that are much more noticeable than on the old format. Also, the related hubs at the bottom are noticeable but not intrusive like they would have been with more of a Pinterest-type format that one of the older versions of the changes had. Remember that?
There are definitely things I like about the new format, so I'm going to give it more time before I decide for sure which I like better.
