Which TV has a (mostly) ad-free OS and works with a few regular apps?

My old Android TV is almost 10 years old and despite ADB modding it shows its age. So I took a look around and quickly found out how bad things have gotten in the Smart TV space.

Dumb TVs are out of the question because of their high prices - they're for commercial use after all.

What I want is a nice big TV (around 65" to 75") with a real colorful, sharp display and an OS that does not annoy me with ads (I despise ads) and recommendations while still fulfilling my needs, which are

• Crunchyroll
• Prime
• Ad-free Youtube client like smarttubenext
• HDMI for console gaming
• Absolutely no stuttering and frame rate issues when playing videos in apps
• Preferably no stuttering menus
• Reasonably priced

Anything else is completely uninteresting to me.

And yes, I know about the nvidia shield, but that thing is 5 years old and I don't want to ride an already old horse that might be replaced very soon due to its age (even though there's currently no signs of that on the horizon). I also don't like using more than one remote...

I have no issue with modding it as long as that's reasonably possible - just to get rid of most bloatware, annoyances, ads and such.

Any ideas?
