I agree; I bought a Vizio TV a few months back. It had all this smart crap built in, but it was pathetic compared to even some of the cheaper AndroidTV boxes you could buy on Amazon or Walmart for ~$40.
New Vizio's are pretty much dumb TVs with built in Chromecasts. Which is exactly what I want. Every Smart TV interface I've used is worse than using my phone as a remote, or Google Home voice commands to control my TV. The experience isn't perfect, but it's pretty good.
I use my Vizio TV for my computer monitor. That's all it ever does is be a monitor. Except when my computer breaks and I have to repair it. For a day or two, that built in netflix app is a wonder :)
