As a Rift S owner, I recommend one! They are exceptionally good if you have a small space to play in, as the Guardian (invisible walls) work very well. The only issue I have encountered so is when the controllers are close to the headset, they will desync. Not the worst thing in the world.
A common complaint is how trash the audio quality is. It's not the worst, it just lacks bass. Recent firmware updates raised the maximum volume limit, thankfully. The Rift S is actually semi modular which means if Oculus ever release a head strap that has better audio, you can just remove it from the visor.
