I owned a Folbot for a while, and while they advertised sub-20 minute assembly times, it was really more like 30, which involved a fair amount of cursing at and struggling in 90-degree weather with the skin that never really stretched out to fit the frame. Moving to a sit-on-top that I can just throw on top of the car in 10 minutes on each side of the trip was a big win for me.
My wife has one, and loves it. It takes a little (but only a little) practice at first to, like, learn how to fold/unfold it, but eight minutes is a very realistic estimate.
I haven't seen a Folbot before, but it looks like some sort of outer layer you stretch over a frame, almost like a tent? The Orus are nothing like that, they're more like origami that you fold together, tightened by a couple of pull straps. And they get easier and easier to assemble over time as you continue to wear in the fold creases. I can (and do) easily set mine up by myself with zero cursing.
Also note every single image each passenger is wearing a PFD.
In a sit-on-top you can flip it back over and crawl back on. In a plastic kayak, another person can empty the boat on their deck and then you can get in. I assume Oru is not structurally sound enough to do that?
That seemed a pretty scary/legitimate criticism.
