No experience with either - but I will say this about folding scooters in general...
Some of them can be really uncomfortable to ride on; that's because depending on how they are made, they often use a slimmer profile seat base to accommodate the folding mechanism. That means less padding for your seat, and over the course of a long Disney day, that could mean your seat is sore from the
scooter seat!
It's not always the case, but if I were going to rent one of those folding scooters, I would try to find real-world reviews from actual users to see how comfortable the seat is; that's really what is going to be the most important.
Also, I as mentioned in your other post, I know you want to be able to fold and carry it, but those tend to be awkward and hard to carry. Don't be surprised - or disappointed or upset - if you find that it's just easier to leave it unfolded, and ride it right on to the bus.
I know that a lot of people don't want to be the center of attention when they have to ride a mobility device up the ramp, but you have to remember that most of the time, Disney veterans will ignore the whole procedure. It's usually the newbies who stare - and the main reason they are looking is because the dang bus wheezes, beeps and carries on like crazy, and then barfs out a ramp! And then it does it all again in reverse! It's really not *you* that is the spectacle; it's the bus!
Also, the number of people who have never seen a mobility device board a bus in the real world is apparently stunning... And, let's face it; there's not a lot else to look at at the bus stop while you are waiting. So, some folks stare (and often I think they don't even realize they are staring, BTW).
But seriously - I thought my Travelscoot would be *so* easy, and I would just fold it up and walk on... and instead I ride it on every single time, and have for years now.
Rent for all-day comfort, especially if you are staying on-site at a Disney Resort Hotel; any
ECV will fit easily into any Disney Resort Hotel room (yes, even Values!) and you will be glad at the end of the trip that you opted for comfort.
Remember - the whole idea is to come home from your vacation happier, more rested, and in less pain than when you left!
