Lift (scala web framework) vs Ruby on Rails

I found this little comparison between the scala lift framework and ruby on rails quite interesting. The points that stood out were that using lift was a using far less CPU usage than rails and that the defects in scala were far less. I would expect scala to have mush less defects due to the type safety but it is good to see a real world comparison.

Though I do wonder how much longer it took him to write the scala code over the ruby code.
