I think that the Mezzo folds faster on account of you don't have to tighten wing nuts on any of the hinges. I've only ridden a Brompton a couple of times but I thought it rode nicely as well. Honestly, had I not managed to buy the Mezzo at less than a third of the price of a new Brompton I probably would have gone with the Brompton just on account of the front carrier attachment. I like the idea of using a Brompton as a touring bike that you could take onto trains as well. Of course, I could do this with the Mezzo, I just might have to use a backpack or something. There's a bag you can buy to attach to the rear rack of the Mezzo, but when I tried to acquire one every online shop I could find was sold out. I'm not sure if they were discontinued or what.
