If the 9barista is as the marketing says then it is nothing like a La Pavoni. One is repeatable via design the other is down to the randomness of various parameters. It depend what you want out of the experience. I have a La Pavoni that I got off these good forums that was pre pimped out and it is a fun experimental thing that you gradually strive to master. But a Hario Switch still gives me a quicker easier drink day to day :-)
I use a K-MAX btw which is more pour over coffee oriented based on the burr adjustment but it does a good enough job for me with the La Pavoni
