webMethods compared to other BPMS


I am a Consultant who uses webMethods to implement processes for customers.
webMethods has good and also some not so good characters features.

Therefore I am currently examining how it would work with other BPM solutions in my weblog http://www.accomplish-bpm.com. I want to get a better overview over the BPM solution market and hope to get opinions from other experienced BPM developers. I would be happy to read some comments from you guys!
