I think as @tompoland says, burr geometry is playing a big part in my findings. I know there’s a subjectivity to it but I’d be surprised if anyone else wouldn’t notice the same as me (thicker body on the flat) with the exact grinders and coffee I’m comparing.
Comparing the Niche to my C40, the burrs on the Niche are 50% larger which will inevitably be making a big difference.
Perhaps a Niche vs a Super Jolly is a better side by side comparison. Even then I think there are too many other factors to say a once and for all ‘conicals taste X, flats taste Y’.
I don’t know how much each of these affect the result but you’ve got motor speed, burr alignment, burr orientation, burr teeth design, how seasoned they are etc etc before you even get into the coffee, age of coffee, how fresh it is, how it’s been stored, if it’s single dosed, WDT’d etc etc.
A lot of factors.
