Not complete nonsense, but some of these points are debatable. I find the Alexa to be simpler to use on a single person/guerrilla shoot. You just hoist the thing on your shoulder, and shoot. You'll need a shoulder rig for Epic, and the menus can be a little trickier. Of course, the fact that the Epic doesn't have a built-in shoulder mount is a huge advantage in other shooting modes!
Rental return is also VERY debatable, and I would be inclined to say the Alexa wins by a margin, but this is an opinion backed by nothing but personal anecdotal evidence.
