Depends on how much you want to spend. The Macbook Pro models generally have faster CPUs so you'll see a benefit there in terms of compilation time and general snappiness.

The MBP gives you the option of the Retina display though. My personal opinion is that that in and of itself is worth the extra cost :P. If you're going for the 13", be aware of the fact that it can be a little bit laggy when you're trying to something graphically intensive. Depending on your use case, you might be better off getting the standard MBP if that bothers you.
