Some personal thought about taste after using them.
General coffee taste
Smooth: Kinu M47 > Comandante C40 > Timemore chestnut X
Complexity: Comandante > Timemore > Kinu

Specific coffee taste
Acidity(Fruitiness): Timemore > Comandante > Kinu
Sweetness: Kinu > Comandante > Timemore

Can you list the grinder names from left to right in the photo above?

From left to right

Timemore chestnut X
Comandante C40
Kinu M47 Simplicity

Very nice collection of hand grinder...
Which one is your fav?

If I can only pick one, C40 would be the one. Because I like complex coffee.
Kinu is more simple and pleasant.
Chestnut X is more like an adventure. It can be quite fruity. Sometimes it's too much. I've tried to mix it with a little milk. It's like fruit milk. Quite interesting.

Looks like Commandante did best, no 1st place but also no 3rd place.
Now you need to compare with 1zPresso K series (or J series).

Maybe you are the person to answer my question.

I have an MC4 I use with my Synchronika for medium roasts.

I have Commadante I use for my pour-over coffee with lighter roasts.

I am getting a Pavoni and plan to pull darker (not oily, just darker) comfort roasts on it. My idea is to get Kinu for that task. Good idea? I do not want to buy Clix and use comandante...

Check out the BPlus Apollo. They tried to give it a La Pavoni aesthetic, even putting the branding on the handle. But besides that, it's a really well-made grinder with a very easy adjustment system (click knob on top, no need to lock). It used to have 30um adjustment (which is a little big for espresso, but not bad for levers). But, you can ask if they have the 15um adjustment available. Also, the catch cup threads on, which some people don't like.

I also have C40, Timemore G1 and M47 Travel...C40 it's my fav

After a lot of online research, I ended up with a 1zpresso JE with the Italmill burr set, primarily to use in a Campervan with a Cafelat Robot. I have no desire to look elsewhere as the grinder is so proficient. I even use it at home. My only gripe is that the adjustments are quite coarse, but once dialled in I leave it alone. Once my MC5 arrives I will probably dedicate the hand grinder for pour over duties at home.
