Out of these two cartridges which would you choose?

I have a ortofon 2 m bronze on it right now and only need the gain nobs half way turned up. So the preamp should have more then enough gain for 2.8mv, plus I have it hooked to a cary cad120s power amp which is an awesome match. I have always owned moving Magnet but never a moving coil. From what my rega dealer told me, In that case I should try the dynavector 20x2. And go for the high output version then I don't need to put more money into a new transformer. The only thing about the 20x2H is its exactly very much the same as the low output version. Though theres a little more zip on the higher top end. But that should be buffered out because of the tubes. And hearing a lot of success with rega and dynavector in the past.

I have been on vinyl engine and people have had better success with the 20x2 with rega then ortofon 2m black. Also my preamp owners manual said the cary slp-98 has enough gain for cartridges low as 1.4mv. Also with the 2m bronze I have to turn the gain knobs half way down because of high output. I was just really wondering is the 20x2 high output version a bit better with bass response and clarity then the black and bronze, thats all I'm looking for I don't want to spend any more change then what these 2 cartridges are. Or on a step up transformer or new phono preamp.

I was leaning nore to they dynavector over the 2m black because I have never had or  tried a mc before. The music I listen to is jazz to Stevie ray and 80's classic rock,and getting more into  modern rap and hiphop/pop and a lot of techno music with lots of bass. So all generes and a good solection of used records. My real concern for the 2M black. I had a dealer tell me that the shabata styleless could Wreck my records because of no propper VTA on the rp8 is that true?
