Anyone? Looking at specifics and what's out there....I haven't looked around too hard yet so I figured I would ask.
Dont know about either other than looking at them but i have the ROKU 3 and i love it. It has amazon instant on it as well if thats what youre concerned about. Theres a ton of preloaded apps and you can get more of course. WiFi signal is amazing as I have mine ~70 or so feet away from the router. And for the kids you can play games on it.
I've never used either of those but I do have several chromecasts and have bought them for friends/family and I can tell you they are amazing! I think they are still on sale for $23 too!
