Which games are the best depends on your preferences which mean there is no single best VR headset for everyone. To figure out the best VR headset for you, make a list of the games you are most excited about and note which headsets are compatible with each.
Generally, the Steam store and the Meta store are regarded as having the best variety of games. The Steam store is compatible with most headsets while the Meta store is more exclusive. The only way to be certain you have reliable access to the Meta store is to purchase a Meta-branded headset.
Because many games are compatible with a variety of headsets, the ones with the best games for you are the ones that fit your virtual reality expectations the best. For example, if you want to see every detail and texture in your virtual-reality adventures, check out the HP Reverb G2 (V2). For untethered gameplay, choose a headset that is either standalone or offers a wireless adaptor.
