Refactoring to Patterns or templates for patterns?

Roman Bosák has published a nice post about rapid implementation of the Singleton design pattern using the Eclipse IDE refactoring tools. Some readers argued that it's much more efficient to use Eclipse IDE templates for implementing design patterns. So, you can see here both approaches, as under 2minutes screeencasts, and you can decide for yourself.

First screencast shows classical (by the GOF book) Singleton implementation using Eclipse IDE refactoring facility (01:10):

This screencast shows a thread-safe lazy-loaded Singleton variant implemented using Eclipse IDE templates (01:40):

If you are interested in more Design Patterns screencasts, please leave a comment, or use our Poll.
