Scroll down to the comparison chart here:

Unless you're the type of computer user who could teach Chuckfickens a thing or two (which is unlikely or you wouldn't have asked your question!) most of the things which have 'No' alongside them in the 'Professional' column (but which have 'Yes' shown under 'Ultimate') are probably completely meaningless to you. (They certainly are to me!). So it's highly unlikely that having those features would be of any use to you.
So, of the two versions of Windows you've mentioned, 'Professional' would probably be the better choice. However, after looking at that chart, you might decide that 'Home Premium' would be just as good for your needs.
