Cartridge choice? Shure M97Xe, Ortofon 20, Empire


Okay so I am stuck between these 3 carts... I have a shure V15 RS on my table now.. However its getting old, and I do like the sound but would like a little higher output, so I figure the Shure M97xe is a good choice, a current model, and cheap.

But I have seen the Ortofon OM 20 super, highly recommended as well, but it is supposedly more anylitical, possibly thinner sounding overall, with slightly more exagerated highs. So against the Shure being very Neutral is this really going to make me frown if I tried it?

Also, I have seen in this link http://www.turntableneedles.com/index.asp?PageAction=VIEWPROD&ProdID=10547

an empire cartridge, of course now out of production I believe from the 80's vintage... It looks like pretty awesome specs. and I have heard a lesser Empire I believe on a Old Kenwood table and it really sounded impressive from what I recall..

So the question is should I not stray far from the shure if it seems they get it done Tone wise?
Basically I am asking opinions as to the superior cartride in your guys eyes(or ears) for what they may do different.

I like very full sound, not to tinny sounding or overly detailed(might be considered bright) or very Dry sounding. And Bass performance needs very good weight to it, as mostly it will play a lot of rock, and more agressive midbass driven material in general.

Thanks for the support

Okay guys I went with the Empire, it looks like a killer cartridge for the money, better output and the sound should be very nice an in-between the shure and ortofon if that sounds somewhat accurate... Plus the shure or ortofon can be purchased anytime, the empire is gonna be hard to try ever again so why not? If I do not like it I will drop only another 80 to go back to the shure if necessary at online cost, they are pretty cheap in retrospect so I will try and maybe get lucky. thanks
Have owned all of these and found them wanting. Of the lot,
the Shure seemed to be the best. Ortofon, second. And,
Empire, third. Of course, that depends somewhat on your
system and your speakers. Beating out all of these has been
the SL-15e moving coil from Ortofon. Not expensive, but
runs circles around these. CEM
Empire edr9 hands down. I'd take it over a MC too without hesitation. Absolutely beast. One of the best ever made. And no low priced MC is going to run circles around the MI edr9. 
I would also vote for the Empire, but.....the cartridge is listed as EDR-9 - COPY.  Beware!
