I would have thought the progression in detail (high frequency resolution) would increase with stylus shape from round to elliptical to Shibata to micro-line, simply because they fit progressively better into the groove.
Many people might prefer a smoother sound with less high frequency, which shoul translate into less transient attack. I have switched from a Shure V15 type III with elliptical stylus to the AT540ML with its micro-line stylus. To my ears it probably is a bit more detailed but without two tone arms or a detachable head shell, I am relying on my memory!
One day I might buy a Jico micro-line stylus for the Shure ... but the entire AT540ML was cheaper!
