Indeed it wins hands down making my laptop sound like an aeroplane getting ready for takeoff with its continuous indexing, while making generous use of the existing memory.
Needs additional configuration for what the others do out of the box, like Javadoc tooltips.
Requires ten finger shortcuts.
It is also the only Java IDE unable to do mixed language debugging, Java/C/C++.
Best of all, I can use Java in any Java IDE.
