I had the same choice to make as you, and I went with the 630. At the time of purchase the 7200 was a little over $200 more than the 630, and I couldn't justify the extra power being worth ~$200 to me. Also, the look of the 630 was much preferred to the 7200, so if you are trying to please someone else, that can always be a factor. I don't think you can go wrong with either.
