What is good:
1) now OWB is multiplatform tool which allow to use any RDBMS as target
What is bad:
1) bug which prevent deployment of processflow packages from Design Center/Control Center Manager
2) by default OWB generate execution unit in Template Mapping with the same name (worlaround - always rename execution unit and that name is unique across target/stage database)
3) substitution API differs from ODI (API calls work in different way than in ODI)
4) new OWB GUI is less usable (slower and provide smaler working area in mapping/processflow editors) compared to previous release
