Hi
Its more depend on , what kind of work you are going to do , which L&F you prefer ,and what is your hardware
1-
Eclipse + Lomboz work well for develping all kind of java application :
j2ee project , standard java project , web developing
Lobmoz is not a royall j2ee designing tool in comparesion with WSAD but you can do your jo on it.(and its OSS

so its free)
it runs on ordinary hardware - 1.7+256MB of RAM - well . you can install and use many plugins from code managment to system modeling on eclipse . eclispe GUI is native so its faster .
2-
Netbeans , you have plenty of good plugins for netbeans too , but not as much as for eclipse.
Netbeans has builtin support for JSP (in Netbeans 4 you have builtin support for j2ee and webservices (AFAIK)
Netbean support for jsp was better than lomboz (I
test them about 1 years ago).
Netbeans 4 has project structure based on Jakarta ANT so it could be a good pros for Netbeans , also having j2ee support out of the box make netbeans more attractive.
but Netbeans need some more resource to run (Its pure java ) , 2GH + 512 MB of ram could be good.
i hope it give you a better view from what you have in your hand to use for your developing.
