If I was in your shoes, I'd concentrate on things such as "is it a good screen / what's the motion processing like / how are the viewing angles / how dark does black get / is the sound any good?" Stuff I would ignore is the smart feature set. History shows us very clearly that TV manufacturers skimp on the hardware and processing power to do a decent job with streaming sources. Instead, they rely on lite versions of the streaming services, and as we've seen with the BBC, after two-three-four years it's no longer economical for the Beeb to keep a dedicated lite service available, so when it closes the TV loses that functionality. You're far better off with something like an Amazon Fire Stick plugged in to a HDMI socket on the set. Buy a 4K Firestick on the next time Amazon does a sale.
