Both are equally good. You can do more things with Eclipse via plugins. For example with Eclipse i code C/C++, Python and Java,J2ME and i edit Latex documents also.
The GUI builder of Netbeans is very nice. I am not sure if there is such thing in Eclipse ( or if there is one it might not be as efficient)

it is just a matter of taste, try both and pick up the one you like.
