The one on the right has poor spacing. The one on the left is a mess, but at least it's legible and shaped like a good page. The one on the right has too tight of a left margin in the right column.
It's amusing how, even though the site is "responsive design", we're all talking about left and right. On a phone the user sees instead top/bottom images. I guess responsive design isn't something you can just delegate to your framework and then forget.
