Gregg,
I know you want the full detailed break down, but I can't provide it. I am not familiar enough with IntelliJ to do a good comparison for you. My suggestion to you would be to make a list of the 5 technologies you use the most (e.g. Spring, code formatting is important, web projects, deployment, GUI design) and then look at how well either
IDE supports those things that you do the most of.
These questions used to be easier back in the day when there were like 3 or 4 IDEs and most frameworks were just a series of config files and a few JARs... now with *entire IDEs* springing up around individual frameworks it's impossible to try and give a line by line comparison about which IDE is "Better", I have no idea what your work flow is.
Maybe I say "we do complete Hibernate, JPA, EJB3 entity generation with Spring integration the best in the industry" and you say "I don't use any of that stuff", then that means that feature has no value to you and you just have to compare the IDEs at some other level.
Some people purchase MyEclipse soley for the DB tools (no joke) because they replace TOAD for them... other people use MyEclipse only because it's based on Eclipse and that allows them to use their 4 or 5 favorite plugins that are "must haves" that NetBeans/IntelliJ could never have.
I really do think the best thing is to evaluate what you do typically during your day, and then see which IDE helps you out the best.
