Hello!
You can find comparisons both at IBM and BEA, but that is marketing stuff of course. Check out the server side for more objective opinions:
J2EE Server Matrix
Homepage Market share of WebLogic and WebSphere is more or the less the same (ca 30 percent each). In Germany it seems to depend on the industry, e.g. WebSphere is very common in insurance companys.
High skills in WebSphere are not very easy to find (at least in Germany). That is why I decided to concentrate on that product. But it is always clever to understand the J2EE-concepts, that share both, in depth.
Greetings from Hamburg,
Stefan
