Good cartridges for a Rega RP6?

Having tried both on my Planar 3 with ADC LFT carbon-fiber low mass arm, I found the Ortofon perhaps a bit better tracker, but
the MP200 better sounding ,at least on the Classical music I listen to on vinyl.

HUH? P3-24 arm will let you know whats what on any 3-500 $ cart.
