Roku devises are the same steaming pile of advertisements. Just because it's a different flavor doesn't mean it's not there. They even advertise in their afk screen. Really that list needs to remove cable because it's also paying to get advertisements and it should include a pc at the front.
I'd put shield ahead of consoles. It's way quicker to start than consoles, uses less standby power (I guess), and the included remote and interface make it easier for "normal" people to use.
Which kinda solves one problem, but you think a non-tech-savvy person will remember not to press the Netflix button on the TV remote that gives them the crappy TV app? For a gamer/etc. that knows what button a TV remote is going to correspond to "o" in the on screen UI, sure. Useful info for those that didn't know!
