I would get the Preciso.
I had a Vario and I replaced it with a Preciso.
I drink manual drip coffee in the AM and drip or an espresso at night - I’m not a fan of french press so my grinders don’t go into coarse territory.
I had 2 nagging problems with my Vario which eventually led to its’ replacement with the Preciso:
I had significant drifting of the levers in espresso territory. By this I mean that the lever would actually move out of its notch during grinding. Pierce, at Baratza, was very sympathetic and helpful with this problem and sent me many shims which addressed this problem. With the shims in place,however, the adjustments were a bit difficult and I often had trouble dialing in the grind. On a side note, I broke two of the the tiny plastic slider knobs when attempting this adjustment.
I also had trouble calibrating the Vario to get a wide enough spectrum. To get a drip grind, for example, I was in French Press territory. Again, Pierce sent me a new burr collar which was designed to broaden the grind spectrum. Even with this new collar, I felt the grind spectrum was too narrow.
I’ve followed a lot of threads on the Vario and it’s clear that my experience is the exception. I know there are a lot of very happy customers who love their Vario. I was simply not one of them. I also have to underscore the commitment from Baratza to make me happy was great.
Nonetheless,I eventually replaced it with the less expensive Preciso and could not be happier. In the cup, which is all that really matters, my drip and espresso tastes just as good to me as the Vario. On inspection, the grinds look very even and I think that Doug Garrott’s appraisal of the conical burr is dead on. The range of the grind is very good and I like the simple adjustment mechanism as opposed to the levers of the Vario. Since both grinders are built with a significant amount of plastic, I feel that less is better in this case.
Whether it will hold up over time is a different question - I’ve only had mine for about 4 months but so far I’m very happy with my Preciso.
