A good question about what do you really need.
I have 2 panels mounted in my home, on traditional tilt type mounts (ie no articulation).
The one on the main floor I have taken down once in 3 years, and that was only because we were redoing the stone on the fireplace, so once I wired it up and mounted it, it has stayed up there.
The one in the basement I have had down 2x in 6 months. That space is a new build for HT, and behind the TV is a series of conduits that lead to elsewhere but are only accessible from behind the TV.
So, if it were me, I would only buy an articulating mount if I needed to swivel the screen with frequency.
With planning, you are likely not often to need to pull the panel off the wall. It is quick work with a friend, but not possible to do on your own (well, I would not anyway, I have 55 and 60's mounted).
