If we’re comparing outright capacity to stop then physics would disagree, unless you have a rather loose definition of “very” or “marginally”.
All depends if you have tested it or not I suppose. I have which is what my statement is based on.
I also qualified my first statement with “All depends where you live and ride”
Where I live and ride there are no pedestrians, no roundabouts, no pavements, no traffic lights, no crossings and very few junctions and most of my riding is not even on the road. Other than stopping to open gates I can’t recall actually having to come to a complete stop at any time this year.
However, if I rode through towns I would have a front brake as I wouldn’t take the risk on an extra metre of stopping distance.
