TCL 75” yay or nay?

My LG was a higher-end unit when I bought it about 4 years ago but it’s now struggling to stream without glitching. Makes watching live events a nightmare. So I’ve been casually entertaining a newer unit.. then I walked into my local Costco last night and was star struck by the combo of features and pricing with the 75” TCL they had on display.

Seems like a fair deal, the app interface on my LG is trash compared to my Samsung and Fire TV’s. Searching always seems to be a debacle.

Any insights or experience with the TCL noted here?
