If it is the definition of a device, each device is different (I don't know which one you are talking about), but generally speaking, Storm Mirror is a mobile phone type, and most of them are suitable for watching TV and movies (note: mobile phones must meet the conditions to have fun), while htc vive is a PC-side device, and now there are wireless devices, so it is more fun to watch TV and play games (the computer configuration can be watched by individuals and basically used). Of course, the more fun the configuration, the better), but overall, HTC VIVE's equipment is more in line with the public's taste, and the equipment is more popular. But since there are all these devices, there must be people who have different choices, mainly depending on the individual. I just give a suggestion!
