In my experience Pi hole is a very worthwhile investment. People who used my internet when I had one would remark how much faster it was. Everything in general seems faster, even things that you wouldn't think of. I typically use Brave for browsing which has good ad blocking capabilities, but this adds a whole additional layer.
The only reason I don't use one now is that I travel a lot more so it's irrelevant, and I have to work enough on tools with Google/Vercel/other analytics that it is just very inconvenient.
Regarding smart TVs, I have found that it's better to just use an Apple TV or Kodi box and never connect to them internet though. Having said, I gave my TV away because I never used it, so this might not be as up to date. A Pi hole will block ads on smart TVs though.
