Transrotor Fat Bob S vs. VPI Aries 3

I'm in the process of upgrading my analog front end. I've pretty well narrowed my short list to Transrotor Fat Bob S with an Origin Live Encounter arm and VPI Aries 3 with a JMW 10.5i arm, SDS, and periphery ring. Any opinions on how these rigs stack up? Unfortunately, I'm not in a position to audition either one.

I listen to many different kinds of music, from small ensemble chamber music to speed metal.

Thanks in advance.
