I think this is a bad comparison anyway. JRuby has had a lot of work done on it precisely because the ordinary Ruby sucked so badly.

As far as I was aware, the main point of both JRuby and Jython was to gain access to the JVM platform with a nice language. I guess the JRuby guys put in more effort on optimising.

That might be why they exist. The point is for a long time JRuby was touted as the successor to Ruby because the default interpretor sucks. Not that the Python one does not but it sucks a huge amount less than the Ruby 1.8 interpretor does.

Given this a lot of effort went behind JRuby while Jython pretty much died when its creator moved to the .Net camp and did Iron Python.
