As a TV nerd
LG Oled is probably the best you can get right now. TCL and Hisense compete against each other at that mid/low cost range but offer really good hardware in the Mini LED Range. Although Hisense calls there technology ULED. The Uled X is a really slick tv.
Personally I have TCL tvs and have been using them for several years. The TCL QM8 is highly rated has a really great picture quality and brightness...however nothing matches oled.
I'm not a fan of LG/WebOS operating system and hate the remote. TCL previously had Roku TV built in but now pretty much everyone uses Google Android TV which is okay. If you are getting an LG, i'd recommend hooking up an Apple TV to it.
Caleb Denison offers really good reviews of all of these models.
My cat just died yesterday, will be getting my basement back now. My ultimate goal is to finish it and hang one of these:
