I’d hope by my choice in machine and grinder it’s clear I don’t tend to just go with popular opinion.
I’ve not ‘blind’ tasted but I’ve done back to back with the same coffee on my SJ and the C40 a few times. I like both grinders so had no reason to favour one over the other.
Prior to these I’ve had 2 Mazzer Minis, Mahlkönig x54, Smart Grinder Pro (we don’t talk about that) and a Sette.
So I suppose the caveat is that I’ve not had a really good electric conical.
To me, conical highlights the more delicate flavours, brings out more acidity and overall has a thinner mouthfeel. These are characteristics I’d typically want in lighter roasts.
The flat to me has a richness, thicker mouthfeel and blends the flavours of darker roasts in a more enjoyable fashion.
To be clear this is exclusively for espresso. I use the C40 for all filter coffee and get decent results regardless of roast level.
As has been said though, it’s all subjective and I’m hardly the authority!
