i have wetek play , mars hd , firestick , fire tv Kodi on every device i use tablet windps , linux ect ect
fire stick is ok for kodi but hey there banning kodi apps on it and wont be to long before they inplament some
algarythim to wipe yer device if its sideloaded (my thoughts they already banned kodi)
wetek works OK with LibreElec installed about 79% off kodi apps will work once installed ect etc
the LIVE TV integration is good , but against Mars thats where it STOPS mars is faster than wetek at most things
and if you use DROID on wetek its same crap EPG NOW AND NEXT as mars is , what are you wanting to be able to do
whats your end goal ? , i set my Mars to boot right into KODI and access the live tv via apps ,android apps , mars tv
fireTV is much better than firestick more ram faster CPU ect etc but i se the BANN on KODI will bite back at end users
at some point , and if your thinking of streaming DVB-S/C from a E2 device to KODI via PVR then firestick just not got enough
memory to be workable 100% it will glitch but FIRETV dont it runs sweet as a nut , when stream from E2 device either VU DUO or WETEK E2 OpenAtv ,
but if you gave what you wanna be able do with new device and what you DO NOT LIKE ABOUT MARS ! rthen it will help anyone give yah
what they think is a good option :)
i have seen the new U4 stb specs and it looks good , but i cant tell yah how the EPG is i do know it does have TVHeadend PVR for LIVETV
so one would assume the EPG will be working a OK , im sure Tony has one, and its a upgrade from MARS with better spec .
