The best thing about this product is that it has all features required for any project which can be used as an integrated solution to develop, deploy & maintain BPEL applications in one platform with complete life cycle management (LCM). There are many tools available today but I feel like most of them lack some key feature or functionality needed by developers while working at enterprise level projects where there needs to be multiple teams involved from different locations/countries etc., so we need something robust enough to handle such scenarios without compromising performance too much. We have been using expressBpel products since last 3 years now and never faced issues till date when compared to other similar solutions out here. It's always good if you get support team who know their stuff very well even though they might not speak english fluently sometimes! So far no complaints whatsoever :) Our main focus right now.
