Also I'd consider Microsoft too. Its Hololens is the best AR device available currently. Although it focuses on enterprise and still clunky to use, the company has quite good track record recently and I have faith in them.
If just Apple vs. Facebook, I'd vote for Apple. Apple would rather kill a product than release anything mediocre or exprimental.
I also noticed it when I play AoE: 2 DE as I only play multiplayer game. I initially thought it's just because there aren't enough players so they match us with someone else much higher. However I only notice it in Quick Play where ELO is not affected instead of Ranked games.
The resolution on today's consumer headsets still isn't there to provide good experience (maybe https://varjo.com/ can work but it's not for consumers). Oculus Quest also last only 2-3 hours after fully charged. Main reason at least for me is it gets quite uncomfortable after wearing it for long (~30 min) due to weight and sweat
