And there lies the age old taste is key
There are differences between them, for me the SSP Hu gave more sweetness and more acidity/brighter cups, I don’t know if that aligns with @tompoland experience with the burr(83mm) but £350 ontop of a £6-800 grinder already…..
For me there are more ways(cheaper) to manipulate brew than just the burrs
As I found with the mp burrs, once you get into them, they are slow, noisy and have a very small adjustment window, then you learn that people are changing brew water and adding drops to get different results, that was the nail in the coffin for them for me.
