> I'm not exactly sure what sets apart some grinder from another. Some say they more evenly grind the beans (similar particle sizes) but I am not sure if that is all there is to it.
Definitely not all there is to it. There are people who are in to swapping burrs on a grinder to experiment with different flavor profiles, or to make espresso vs filter coffee. Some grinders even cater to us, such as the Niche Duo: https://www.nichecoffee.co.uk/products/niche-duo?variant=431...
Also, some people who like more traditional, chocolaty espressos prefer grinders/burrs that produce more varied particle size. People who like cleaner, "modern" espresso prefer grinders that produce the more similar particle sizes.

It's a rabbit hole.
