I'd say it depends ;) 5.0 is faster when it comes to Swing/GUI stuff, but I do
not see a big difference for non-GUI code. I'd go for 1.5 just because it's the
most recent version (and 1.6 is "on the doorstep" already)

The only thing you need to consider: if you are writing applications that have
to run on 1.4.2 you have to be very careful which API calls you use and how you
compile your program.
