I think a lot of the "hyperbole", if there really is any, is a reaction to the common conception the EV world is fighting. Many people, if not most, still think EVs are toys. Tesla has gone a long way toward proving electric cars don't have to be glorified golf carts, but I think people still think "cheap Chinese scooter" when you mention electric motorcycles to them. Including most of us until we learned differently.
Again, for not being all-out sportbikes, it really is surprising how much performance these bikes give you. A really surprising amount, enough to put them way toward the top of the list for general-purpose bikes. The almost mind-reading responsiveness of the bikes only enhances the feeling.
So yeah, we probably tend to exaggerate a bit out of our own surprise and in order to stress that these are NOT cheap scooters. But nobody should be "caught out" by that sort of thing. Didn't you test ride the bikes before you bought them? If you didn't know exactly what you were getting before you made a purchase this major, you just didn't do your homework, and that's on you.
