If you go by looks alone, then, in my mind Mezzo wins hands down. I bought one. It rides good. The chain never falls off. It is a solid, yet comfortable ride. I like the saddle. No flex that I can feel, except maybe in the folding pedals. I don't like the pedals. Mine is the four speed hub model. The shifting is smooth. The bike climbs well. I wish I had a higher gear.
The new Brompton with the 31 to 99 inch gear range looks like it will be a winner, if the chain stays on and one can get used to the awkward shifting.
They are both good English bikes.
