My edges got smoother with more experience, and not with magical stones. My edges off of my 12k Naniwa were much harsher two years before than now. Those wich I get nowadays from the 16k Shapton and 10k Naniwa are both sharp and smooth, a very nice comfortable shave.
I used to have eschers, jnats, cotis and such, but you don't really need a 200$+ stone to have good shaving edges. They are different, yes, but don't expect that the edges off those stones will be much better than your synth edges.
