Why do I have 2 kinds of Pages on Facebook?

I’ve created 3 Pages. One of them (the 3rd one in the image) looks different.
It is also different inside. For example, the 3rd one has its profile photo on the left, but the 1st and 2nd have them in the middle.

How did this happen? What is the difference?
Which type is better? And can I change a page’s type?
