I wouldn't argue except to say that over the years I've owned quite a
number of bicycles which undoubtedly had varying BB width... and I've
never been able to tell the difference. I've never jumped on a bike
and thought "Gee, those pedals are a long ways apart" or conversely,
"Gee those pedals are really close together".


I think "Gee those pedals are a long way apart" when I ride my MTB.

It's another reason I don't like riding that bike, and why I bought a
gravel/touring bike that has a similar (if not the same) Q factor as my
road bike.


Out of curiosity what is the difference in BB/crank width ?


I too was curious, because I remember it feels noticeably wider but I
didn't know off hand by how much, so I measured it yesterday before I
replied to you, in case the feeling was in my head. Nope, the
difference is 20 millimetres, as near as I could measure to the outside
face of each crank. 160 mm to 180 mm.
