My favorite finishing stone (s) with slurry is an easy question for me but ask again next year and it may be different. Right now though it is a thuringian (light green from Hatzicho or yellow green Hohenzollern stone) with slurry from slurry stone from Hatzicho and a jnat with many different slurry stones (nagura).

The jnats have provided a SLIGHTLY keener edge retaining the smoothness but the thuringian stones are MUCH less effort for me at this time anyway.

A translucent or surgical black Arkansas stone is also an amazing edge but if you don’t have patience and like working with slurry I wouldn’t look in their direction.
