There's Ruby 1.9, the language and then there are
implementations. JRuby lags behind in 1.9 compatibility
(understandably, because 1.9 has been in flux until very
recently).

Ruby 1.9 has some nice features like the encoding support
and the earlier the Ruby community migrates, the better.

Regarding performance, I have a rails app running on
JRuby and it's actually slightly slower than MRI 1.8.
