I’m British, and if you offered most British people “a muffin” they would assume you meant the American style sugar and oil affair. Some people do enjoy an “English muffin” but they’re not very popular, much less loved than crumpets, which themselves are probably below scones. The main use I see of them is as the base of Eggs Benedict, which works because they are basic and go well with butter. A white chocolate & blueberry muffin is a much more controversial paring for poached eggs and hollandaise.
