Apple TV with Infuse, hands down.
I'd go with a Roku next. The Shield is in third place, in my experience. Fire TV, which is built on Android, is a UI mess, with ads to boot.
I personally find Kodi to look like something from a decade ago (maybe I should try a few more skins, but...), and MrMC is not much better. Both are functional, but in terms of UI and flow, Infuse is in a whole different class.
I used to use Plex, but since I moved to Infuse, Plex with its server (which I find to be a bit of an unneeded hassle) is gone from my devices.
Apple TV and Fire TV are the only ones to support Dolby Vision.
