Cutting the cable, lets talk options and media setups
To be honest, Cinema, CyberFlix, TVZion, Bee TV, Titanium, Tea TV, Typhoon, and about 10 others are all pretty much the same if you link your Real Debrid. The reason I like Cyberflix is it's a direct clone of Terrarium, which my wife got used to using before it died.
But when I set up a Firestick for someone I usually put everyone of them on there. those apps are like vehicles, everyone has their preference. I let them choose which one they prefer.
TVZion with RD and their club membership is pretty good if you have a 4K TV and don't have to worry about a data cap (like I do). It pulls some very impressive links.
But Trakt has made it so much easier for us to keep track of what shows are watched across all devices and all apps.
Heck, Real Debrid even makes watching stuff on Kodi bearable.
