tl;dr Ruby 2.1 is the fastest MRI yet. Rubinius is on par with if not better then most of it and exceed it in Concurrent test.

I see there is LOTS of potential with Rubinius 2.0 Finally there is a modern Ruby Implementation.

Not sure if I am naive, but I always wished Rbx and MRI merged.

A lot of Ruby newcomers don't know about all the different implementations, and the "slowness" of MRI turns them away! :(
