I recently got a smart TV, and I use the netflix app built into it, as well as the general video player for playing files I have on my computer's media server... But I used to just use my Playstation for that before I got a tv with the apps.
As long as the tv has import ports I can use other devices than the TV itself to get content so I'm not really concerned about that.
I bought the TV because it was good at being a TV - that is, it is OLED, high res, good upscaling, etc. The "smart" stuff I could take or leave, but I'm enjoying the convenience of it while it works.
