The compliance rating of the cartridge and its compatibility with your tone arm to avoid unwanted resonant frequencies must be taken into account too.
I assume your Radius has the Roksan Nima tonearm. If so, its effective mass is 10 grams making it a good match with any of the three MM cartridges you mentioned in your original post. If you have another tonearm, then this could be a different story and resonant frequency of the cartridge/tonearm should be re-evaluated to insure a proper match.
Of course just because the compliance match is right, they will still sound different and I would encourage an audition of each if possible. Cartridges, like speakers, are transducers and each brand will sound quite different from one another.
I will throw another in the mix for your to consider also - the Nagaoka MP-500. Sorry to further complicate matters but this cartridge is another world class MM cartridge and deserves to be in your group. Good luck!
