All .3x.7s sound spitty. The AT 120 is another example. I use one on records that are kind of muffled or weak. It is a live sounding stylus for a room full of people, or new records.
A .2x.7 is a finer sounding stylus, but fine means clean but weak, but it does have some detail.
The .4x.7 is a smooth, warm, and full bodied sounding stylus that sounds good on most records.
Sphericals have their merits, they aren't usually spitty, but on a good record the sound the most natural.
Stanton supplies .3x7., .4x.7, and a spherical for the 681 EEE. The .4x.7 is the one generally recommended as general purpose. The opinion of a Stanton owner and fan that uses one regularly would be important.
Regarding the JICO, I would want to be experienced with the originals before chosing a generic, but the nice thing about generics is you can out do the originals on the right albums, and get your own customized sound if you know how to modify them. For example, I don't want to cover my original stylus with damping materials (and the packing sponge in the case of a Finetone is good for gluing onto a stylus knob). Just realize that many complaints have been made about the fit of generic replacements including the JICO V15xMR. I call that "adjustability", and is one of the reasons I like generics.
