I've only ridden the fair version, but they one I rode was a ton of fun with one op, but sucked with another... So it seems for the traveling ones that the op running it makes a real difference. As for comfort the one I went on had almost unpadded shoulder restraints so it gave some gnarly friction burns on my bare shoulders after the 3-4 ride, but if you're wearing a t-shirt or long sleeves you should be fine.
