Looking at getting 3 wall brackets for TVs sized 48, 50 and 65"
I want them to be able to swivel left/right and tilt up/down. I think this checks the boxes. Trying not to pay an arm and a leg but if you gotta spend more to get quality please let me know.

Weight wise I realise it's overkill, but I'd rather it that way.
And possibly this one for the 48"

I used to import TV wall mount brackets as a business, make sure the back plate fit the typical stud placement of your wall (if brick veneer home) - many brackets have a wall plate that is not wide enough to straddle 2 studs and be secured by 2. A 65" TV isn't something you want hanging from gyprock alone.
