No I'm too lazy to document the flavour profiles and it's also hard to directly compare two roasts side by side, as I would never drink two cups back to back.

I just trust that the small coffee shops where I buy my coffee from don't lie to me when they slap those fancy labels with the origin details onto the packaging.

In general, all beans from big brands that you can buy in a supermarket are usually blends of beans from many different plantations - there really is no other way for them to produce such massive quantities and guarantee a consistent flavour profile. So by just mixing all beans from 50 plantations, you get some mediocre tasting mishmash, but at least it always tastes the same all year round, everywhere in the world (ie that's why Starbucks tastes the same everywhere, but it tastes like ass).

The single origin beans I buy from small artisanal coffee shops are usually just available in very small batches and for a short time and after that they are just gone for an unknown amount of time. So there really is no point in knowing what my favourite would be because I would have no way to keep buying it anyways.
