Those are basically it when it comes to currently in-production headsets. The Cosmos shouldn't even be considered, it's completely garbage compared to the inside-out tracking of WMR headsets, let alone Oculus inside-out. HTC fucked up and rushed it out to compete with the Quest before they'd figured out the tech.

If you can find old stock or a used headset in good condition, the Samsung Odyssey Plus is the best WMR and was quite cheap, but it's no longer being manufactured. The Reverb G2 will pass it anyway when it comes out. Quest 1 headsets aren't being manufactured either, but they have the same panels as the Odyssey+ and can do the same standalone link tethering as the Quest 2. 

Not sure I can recommend the Vive Pro because it costs as much as an Index for again the same Samsung panels as the O+/Quest 1 but it's still being manufactured, Maybe you really like OLED and also want Index controllers and have infinite budget I guess you could mix those systems idk
