Which Version of Adobe Photoshop Creative Suite is the best?

     I have not been able to work with all of the versions of Photoshop, but out of CS6 and CS5, the two that I have had the pleasure of working with I think that CS6 is the better one. They are always adding new things to these programs and CS6 has the most updated features which I like. Some people however like older versions because of they have become comfortable with them, they don't want to make the change, or maybe it costs to much to upgrade. I would be curious to know what your favorite version is. Leave a comment explaining why you like a certain version of Photoshop Creative Suite.
