Yes, its true scwcd has got more topics to cover then the scbcd...and from my personal opinion i find scwcd is more intersting then scbcd....
I personaly gained a lot in taking the scwcd exam...which i apply in my projects....
To cover the J2EE i think it would be better to go in steps...SCJP--->SCWCD-->
SCBCD--->
SCEA...
And also depends on what area your currently working...its better to be master in wat your doing then looking at other things(nothing wrong)...
Sai.
SCJP,SCWCD, SCBCD (preparation )
