comparison of intellij vs springs grails IDE

What does intellij do that other IDEs dont vis-a-vis grails? Im trying to decide whether I s开发者_如何转开发hould renew my license when it comes time.... thanx...

Discussing about IDEs is a highly religious task, so the following points are my personal opinion. IntelliJ's advantages are IMHO:

• Debugging works better
• GSP content assist
• DSL awareness
• better refactoring support for Groovy
• Grails project view
• Integrated UML diagramm of domain classes
• synchronisation of dependencies
