Differences in styli

So I am considering a EMT TSD15 for my Amadeus and the cartridge comes in two different options, spherical or super fineline stylus, I have heard this cartridge with the super fineline stylus and I loved it. My question is what are the tonal/tracking differences between all different stylus varieties? Is this even an answerable question since the cartridge's and the cantilever's interaction with the stylus influence both of these attributes?
