Orig Grado Sonata vs Grado Platinum 1?

Which is a better cartridge. Vpi Nomad with Grado Rs2i headphones hooked up to it. I can get the Grado Sonata, old version for
$250.00 with 75 hrs on it. Newest Platinum for $350.00 new. Which is better? Can't afford newest Grado Sonata at $600.00. Thanks, Gerald.
