"There are much better alternatives out there..."
...and I would've thought a good starting point would be: why buy a "smart TV" in the first place?
I've learned the hard way about "planned obsolescence" in this kind of product, when in 2010 we bought our Sony Blu-ray player (with added network media facilities - LOVEFiLM/Amazon, BBC iPlayer, YouTube, etc.), and a "dumb" LG flat-screen.
By early 2015, iPlayer and YT had both stopped working, thanks to the APIs they relied upon being phased out by the services in question. Now, the BR player lives on solely as a way to play BRs and DVDs, with all network-based video-streaming duties handled by a Roku device (Streaming Stick, at time of writing) plugged into HDMI on the TV.
Point? At least in this case, the loss of iPlayer and YouTube was fixed by a ~£35 HDMI dongle, and the BR player was still partly useful afterwards. I'd feel sick as the proverbial talking avian, if I'd coughed up £100s (or more) for a "smart" telly, only to be left high and dry a few years later when the manufacturer decided it was time we bought a new set off them.
Personally, I'd rather add "smart" capabilities to a "dumb" TV via a plug-in device which can be replaced when it (the device, not the telly) becomes obsolete, but that's just me...
