Current state of Quest 3 Augmented Reality - Worth purchasing a device?

I have been going back and forth for weeks about whether a Quest 3 is worth getting. I have never owned any kind of VR/AR headset before and only recently got a good GPU capable of rendering most games.

Augmented/mixed reality is what really drew my attention, especially that reddit video of the guy battling enemies in his house using Blade and Sorcery and a Virtual Desktop. That looks awesome! I have a forest in my backyard and the thought of simulating ambushing a Roman legion in the forest with real movements gives me goosebumps.

However, I have no idea how well any of this stuff actually works, nor what the support for mixed reality actually looks like currently. If it's all a buggy mess that will just give me motion sickness I am not interested.

How useful is augmented reality in its current state? Can my dreams of running around like a cyber psycho in the woods be realized? What do augmented reality tools look like for things like construction or forestry?

I can't really justify it just to play ping pong, but can also imagine some really cool uses for it. Thoughts?
