I would suggest reading the cartridge loading thread viewtopic.php?t=6674
A major part of the difference between cartridges is related to optimal loading - by adjusting the loading you can make them sound much more alike.
With the Audio Technica cartridges as an example, I prefer to run them at around 32kohm rather than the default 47kohm - when set up that way, the rising top end is tamed, and they become much more neutral.
The Ortofon's have a similar rising top end (slightly less pronounced)- and can similarly be adjusted with loading.
The M97xE can also be helped with some adjusted loading - good article on the topic here:http://www.tnt-audio.com/sorgenti/load_the_magnets_e.html
The top end Shures (V15VMR, ML140) were very very neutral, as were the top Stanton's and Pickerings...
