Well, for lack of better advice, you can see which one had more marketshare, or maybe search on a job site and see which jobs are more prevalent. If there's a particular domain (e.g. bio, academia, web services) you want to go into, maybe one is more common in that space. Or maybe you could glace at both (invest an initial 10-20% of your time) and see which looks more promising to you. I suspect the time might may off, as both are similar and you might start to see larger
patterns and/or whats confusing with one, might be clearer (and similar) in the other.
Of course, when in doubt, there's the tried and true method, a flipping a coin, and then committing yourself 110% to the
J2EE vendor religious war, forever scorning those who chosse differently then you. Head blood, tails cript. (Those the names of the major J2EE providers, right? :-p )
