I'll stick with Chrome it's not optimized for ATV but I still think it's the best browser out there, however I'd like to add two more to the list that are optimized for Android TV that no one has mentioned yet the first is milked - smart web browser and the second is Puffin TV can't vouch for one or the other as I haven't tested them but they are optimized for Android TV, Puffin is the newer of the two, Cheers ��
Also you can try Mouse Toggle if you want to use your remote directional pad as a mouse, it's compatible with the Shield TV, Mi Box and Nexus Player, and I don't think this version of the app requires root, again haven't tested it, but can be useful for sideloaded apps :)
