I always like to hear both instruments played by the same person in the same setting when making a comparison. theguitarsyndicate on youtube has a sound clip of both. It's short, but it may help.
Not being able to try out ukes in person is painful and I think a big contributor to UAS. You just keep buying and trying until you find the right one instead of just going to the store and dropping tons of cash on that 1 out of the 100 on the wall you fall in love with. It's like buying wine from the market. You never really know what you're going to get. No matter how closely it's described, nothing substitutes for tasting it in person.
