Recently looked at buying someone a shave brush as a gift and when in the store looked at the large (23mm) and the medium (21mm) models, they looked about the same but the large looked fuller if that makes sense and the handle had a bit more meat to it, I have a medium size merkur but eventually saw myself stepping it up to the large size, didn't know what people preferred here, if they found that the medium size is the sweet spot as it is easy to maneuver and didn't use too much cream, or if the large size is typically preferred?
