First You need to know what degree You want. The variety offered is large.
A better approach would be, to find out "what do i need to know?"
Then consider all sources for this knowledge. This means self study (by book), offline or online. Then take the one which fits Your needs best.

I personally don't like online degrees, because they are too expensive mostly. You pay tons of money, just to receive some copies of PDFs (as far as i know). I think there are only few online learning programs that offer quality for a fair price. Ask for example lessons.
