I have a Bezzera BZ10 and an Ascaso I2 and I am thinking of replacing my grinder with a new Baratza Vario or a used Mazzer Super Jolly.
What I really want to know, is it worth it as far as grinding quality is concerned?
Am I going to be able to extract a noticeable better espresso with the Vario or the Jolly than the Ascaso?
