I am not sure of the kw you want to rank for, but the on page optimization on the second page is much better than the first, while the layout of the first page is way better than the layout of the second page.
According to Moz (the fancy Moz Toolbar) these pages are very similar. A test you can do is to swap the Meta Data on the two pages, wait about 2 weeks to make sure they get crawled and then see what happens.
You can also optimize your internal links a little to put more juice to the page you want to rank. Depending on the keyword, this can help. How old are these two URLs? The difference could just be the age.
If you intend to permanently get rid of that second page, you can redirect it and the added juice might push the second page up to where you want it. However, if both of these pages serve a purpose somewhere I would not do that.
