As others have mentioned at this point it would be wise to wait a little if you’re not in a rush, at least a few months.
Of the currently available headsets the Reverb G2 is arguably the best supported one for MSFS, but that doesn’t necessarily mean best overall, and every headset comes with compromises…
Reverb G2: Reasonable price, average fov, but tiny sweet spot, no longer in production and no successor planned, a possibly soon to be deprecated platform, and has issues with lateral tracking jitter on win11. Still, it’s well supported and there are proven workarounds for most issues, including performance issues, has good audio, and it’s as plug and play as headsets get outside of meta.
Quest 2: Inexpensive, decent performance in most areas, very plug and play, but average fov, and comes with all the issues a meta headset entails.
Pimax Crystal: On paper arguably the best near term option for simming, but with some caveats. Good resolution, inside out tracking, slightly above average fov with potentially wider fov lenses available at some point, but with somewhat dubious software. It’s also bulky and heavy, and its dependence on batteries is a fundamental mistake in my opinion, and it’s not yet a complete proven package with all functionality enabled (eye tracking etc). It’s also fairly expensive. Worth waiting for more in-depth reviews and software updates, which are starting to trickle in now.
Bigscreen beyond: Nice on paper, extremely light, small form factor, good resolution and colours, but tiny fov, no built in audio, and expensive, requires base stations.
Varjo Aero: currently the best proven headset available for raw resolution and clarity, and with very solid software, but average fov, no built in audio, and extremely expensive, also requires base stations.
Pico 4: Good resolution and colours, average fov, but serious and unnecessary performance penalties from being forced into wireless mode. A wired displayport version of this would be great, if it ever happens.
Most headset manufacturers these days are prioritizing form factor, weight, and wireless play over everything else, including performance unfortunately, which is the exact opposite of what we need as simmers. Even among wired headsets there’s a big difference between native displayport models and USB ones. A native displayport connected headset wins every time.
The only headsets designed with simming specifically in mind are the Varjo Aero and Pimax Crystal, and to a lesser but still valid extent the Reverb G2. Everything else is a compromise on clarity and performance due to manufacturer prioritization of standalone functionality. The bigscreen beyond is kind of a weird outlier. It’s wired and light, which are great, but the fov is so low I don’t think it will ultimately have a lot of pull with simmers.
If you’re in a hurry the Reverb G2 and Quest 2 are probably the safest interim headsets to buy. If you can wait a bit I would see how the Crystal shakes out over the next few months.
