Netbeans
+ has UI builder
+ works on all platforms
- no more object browser (this is very bad)

Eclipse
+ has refactoring
+ has real time compiling
+ shows class or method usage (very useful)
+ works with C++
- no UI builder
- slow on linux
- no mac support

Both have
+ Code completion
+ ant integration
+ modules

in the end.. eclipse is much better at this point.
(unless you need UI)...
