We’ve used them twice in Orlando so far, have used Gold over 10 times, and Buena Vista only a few times (found their time windows hard to plan around).
They all have their pros/cons. How much each matters will depend on the individual.
What I really liked about Cloud of Goods was the lower cost and much better choice of pick up and drop off times. The first time we were able to give it back very late, meaning we were able to close MK that last night. The guy agreed to come to Grand Flo at 11pm. We used them again last month for a short 4 night trip not only because much cheaper but so we could have it late that last night… and they ended up asking if we could just do 8am the next morning for no price increase (charged only 3 nights), which worked beautifully.
Where CoG is not as good is upkeep. Gold has always been very good at maintaining every detail to a high standard (the pricing has just gone up too fast). CoG not so much with the upkeep. We didn’t have any problems due to that, but the condition was a bit beat up and the charge socket loose. One thing to note, scooters may show power going from green to orange and even red, then go back up to green when it switches to the 2nd battery onboard. We just kept the power cord in the seat pocket and even though sometimes it looked like we might run out of power, we never needed to charge in the parks. Just charged daily overnight while sleeping.
Going forward I will likely flip flop between CoG and Gold depending on prices and what kind of trip we are taking.
