Websphere does not run on Windows XP, so you will have a hard time learning with it if that is your home platform. Websphere is the most popularly used, with Weblogic coming in at a close second.
Personally, I feel that once you learn one it is a very small matter to learn another. If you can run both servers on your machine, download both. Spend a day on each one, see which one is more intuitive, or does not have problems on your operating system, then purchase a book on the one you decide to start with.
