The grind quality on the 3 grinders you mention is exactly the same,
The opening in the top of the grinders is the same diameter & the hoppers will interchange
The dosers vary in height but not diameter & are not interchangeable
As the grinders increase in size the adjusting rings also increase in diameter, but the spring tension also increases, adjusting any of them is about the same, the larger ones might be slightly nicer
all of the grinders offer a few options like timers, auto on / off, counters etc

I have to respectfully disagree with the above statement. We have the chance of have all 3 grinders (mini, jolly, major) in the same room and observed that, as you step up with size:
- shot to shot consistency improves - grinds gets fluffier - which results in less clumping and improves dosing/distribution - the clarity of the shot improves (i.e. flavors become more distinct and layered) - pop-corning becomes more severe
I do not have a MINI right now but I do have a CIMBALI jr & just sold a MACAP & a SJ, I still have three RIO's super auto's, I have restored & sold 23 of them.
Anyone that can taste the difference between these grinders has taste buds way ahead of mine
Look at the burrs, they are all the same design. Where does the difference in taste come from.
I do have my favorites, the big RIO's & ASTORIA's are great, but the CIMBALI I just got is very nice as well. it does not grind any better / worse than a Mazzer SJ. I suspect that the burrs are interchangeable. Anybody know for sure, the mazzer parts are cheaper & easier to get. yeah, I know, mazzer parts are expensive but Cimbali apperars to be more expensive. Aristo wants $104.77 for a hopper, someone has to be a little cheaper. I have only had it for 2 day & have not spent too much time looking.
I would appreciate it if someone could explained to me why a mini normally brings more on EBAY than a SJ, and why a SJ usually brings more than a major, there are exceptions but generally the above rule applies. In my book the Major is far ahead of the mini . I normally purchase the larger grinders, I prefer the RIO's & Astoria's
Just a guess...They all have same throat-feed size and rpm. Concepts; Bigger burr set =less heating. Bigger motor= more consistent torque= even grinding. Cooler- even grind= better taste. Major 83mm burr set 650w motor, SJ 64mm, 350w. Mini 58mm 250w. Winner in my opinion is the Major. I don't use a hopper with my Major (just pour beans in throat and have a ss large salt shaker top that I use as a cover) that way it just fits under my cabinets on the counter. Ed
The larger burr sets turn slower & heat the grounds less, but for the home brewer I'm not sure the grinder will be on long enogh for heat to be a problem. Of far importance is the condition of the burrs. I just put a new set into the Rio SJ I'm selling & the improvement was amazing. I could grind finer, get better extraction, and more crema, because the particle size was more consistent.
In the picture of the machine you can see an after market hopper I bought on eBay. The size is perfect if you've roasted several SO batches & like to switch back & forth.
"TEX" has a good point, new burrs make a big difference, as I see it sharp burrs cut the beans, dull cutters break the beans.
I put new burrs in every grinder so all my experience has been with sharp burrs
I should have expressed my views as an opinion , the statement came across as a fact, sorry about that
Can you guy's live with " I can't taste any difference nor can I see any difference in the quality of the grind in any of the upper class flat burr grinders"
I did mess with a conical grinder where I could easily see the difference, they were fluffy, I did not get to taste test
