I have a few option, well to be honest I have 10 different hardwares to play LE in right now.(2 Rpi3, 2 Android boxes with S905 and S905X, 6 HTPC:s with different harware all from Intel Graphics, AMD and Nvidia).......
And if only the main porpuse is to: playing 1080p videos (H.264 and VC-1) and letting kodi put out LPCM 5.1 sound with LE 8.2.x
I found the most stable and reliable Hardware until now to be Raspberry Pi3....
With both Android:s and HTPS:s, I have a few problems that I remember, all different types, cant mention all of them now, but cant remember any so far with Pi3...
With the most stable I mean: no hickups, no stutter, no black screens, no strange audio fenomen or other weird things happening....
With the most reliable I mean: Easy startup, compability with other hardware like usb drives, usb sticks, mouses and keyboards. And also the boot and the way it feels stable when in menus...
AM I RIGHT? Or should they all perform flawless, if everything else in the chain is perfect as can be..
