Wading into the discussion here.
I've convinced a few friends to get a Preciso, many were skeptical because of it's price assuming it's of lesser quality than the Mazzer, got to love price fallacy arguments.
There was one problem with a Preciso, a friend broke the fine grind retention collar of, the C shaped plastic collar than the fine grind adjustment clicks onto to, we have super-glued it back on and it's working fine, but it's worth mentioning.
Secondly getting portafilters into the Preciso isn't the easiest, some are a little bit to wide, and distribution into isn't the best and requires a bit of readjustment with a finger or implement.
Having got those two cons out of the way, I am incredibly impressed with this grinder, and have to say its the best home grinder i have had the pleasure of using.
In fact, a friend was so convinced of its quality he took it to his cafe and ran it against a Robur, doing blind tastings (I have run it against a BNZ conical at the shop i work at) and we couldn't pick the different grinders. Think of that what you will but if you can't discern the shots between a Robur or a BNZ against a Preciso its a pretty good endorsement. Maybe a better palate could, but when adding 6 ounces of a milk, i doubt anyone could.
Another huge tick for the Preciso is grind retention, its about 0.5 of a gram. Which is marvelous, it means less wasted coffee, no purging every morning to get that 3-4g out to have fresh grinds, and for precise dosing it means that what you put in is pretty close to what you get out. It also doesn't popcorn much, meaning its viable to put 22g of coffee in and run it through and not suffer coarser grinds at the end, Mazzers on the otherhand popcorn quite badly.
Pro number 3 is the adjustment, it makes filter to espresso a dream, really the only home grinder i can think of that makes it easy to switch without wasting coffee. Now for a lot of people they only make espresso, but they have that covered with the fine adjustment collar.
So where does this leave the Mazzer? A distant second place in my book. For a start i would never recommend or get a Mazzer Mini doser, to much wastage, doser is badly designed, its just not for home use. Leaving the Mazzer Mini-E, thats $1k worth of grinder, and it can't do as much as the Preciso, and is slower and suffers from worse grind retention, and switching from Filter to Espresso is tiresome and tedious.
The Mazzer looks nicer, and has an italian heritage behind it, and a lot of people that have a vested interest in selling them on this forum, but in my opinion, it isn't a suitable home grinder, and the Preciso wipes the floor with it in almost every way.
Disclaimer, i have worked with a Mazzer mini in a commercial setting, and briefly had one at home, I don't own a Preciso but have used friends fairly extensively as i plan on buying one soon.
TLDR: Preciso: a $300 grinder that outperforms an $800 Mazzer for home usage.
