Great value for espresso, but clogs and poor for pour-over.

Does it have to be a single dose grinder? I see everyone is going that route since you are coming from the Niche and were considering other single dosing ones, but with that kind of budget you could get some nice grinder with grind by weight integration and a little 250gr hopper... On my side going from the Niche Zero to a Eureka Atom 65 high a small hopper has been an amazing upgrade in term of workflow, and the only thing I'm missing is grind by weight. But the fluff of the ground on the Eureka Atom mean I don't even do WDT anymore, just some tapping and I get a much better puck prep than with the Niche where I was doing it all, RDT, WDT, etc. I'm definitely not missing having to wet my beans to avoid retention and all. Overall I find myself never using my Niche anymore except for decaf, but it's true I don't mind swapping beans only once a week and going through a whole pack at once instead of having a rotation of 3-4 different kinds.
Atom 65w amazing grinder.
I use a Eureka Atom 65w, I highly recommend it for both grind quality and ease of use.
I have an Atom 65w and have had nothing but a really positive experience with it. It's definitely built more robustly then the Mignon and has dedicated espresso burrs, it's also much more solidly built and heavier than the Mahlkonig E64ws. If you like your Firenze maybe it's worth going up to the Atom 75w for you.
If you're in SoCal I'll sell you me Bianca and Atom 65 grinder together for $3000. Just ordered a Linea Mini
The Atom 65W is a cut above the others. It’s more sturdy and substantial. My second choice would be the Malhkonnig. I have heard the the Allground has high retention and loses your settings when you open it for cleaning. The Eureka adjusts from the bottom. Also their ACE anti static system leaves you with super fluffy grounds in the basket (not clinging everywhere). Both will hum out an 18g dose in about 5 seconds. I love my Atom.
I have a Varia (VS3 and 3 different burrs for it). I really like them. I upgraded to my Eureka Atom 65W for the same reasons (fast, convenient, good), but kept my Varia for the one-offs. Very low retention is an advantage. If a VS6 is in budget, go for it!
I really love my Eureka Atom 65W. (There is a 75W too). It’s fast, fluffy, non-static and grinds the exact weight you want in seconds. In your budget. Eureka’s build quality and excellent burrs, all made in Italy. 🇮🇹 (Great balance of clarity and body with Medium to Dark) 😍☕️ Lower retention, less clumping, faster and easier to adjust grind size down than Fiorenzato AllGround.
If a Eureka can be found in this price range get it!! 😎💪 The real deal
This is my experience and recommendation to a T. lol. I even make the same amount of espresso.
I have the atom 65w; got it maybe 6 weeks ago. Game changer for the workflow and super accurate
