itsavi007,
We appreciate you considering MyEclipse for deployment in your company. The fastest way to get up to speed on our tool will be to start with our feature matrix here:

And as to what we add ontop of Eclipse + WTP… use use Eclipse + WTP as our platform that we build on, so every other functionality we bring to the table like XFire WS client generation, web service generation, Hibernate + Spring integration, Hibernate and JPA reverse engineering, EJB3 reverse engineering, 30+ app server management and deployment support, Swing UI development using the much-famed Matisse designer inside of Eclipse, full DB Explorer visualization/editing/running and a list that goes on… I could think of *a lot* of reasons why MyEclipse is worth $30 more to you over the base Eclipse + WTP package.
But then again, I’m biased 🙂
The best way to do this evaluation, and the way we have seen a lot of our enterprise customers do it, is to choose 1 or 2 applications as models, and then work on them for 1 week apiece in each IDE and record your experience as you go. At the end of 2 or 3 weeks, depending on how many IDEs you are evaluating, sit down and compare your notes and see what you liked and disliked, get in contact with the vendors to address those questions and see what you think.
