I think Continental is faster and puts less strain on the wrist. I used to be a Continental knitter but have now switched to Eastern knitting. This is used in South American, Eastern Europe, and Arab countries. What I like about it is that it gives you even tension. The yarn is always in the back of the needles, even for purling, so you always keep a steady tension on the yarn. There's not much online written about it. Here's a great site that I learned it from.
