First of all, PSV is a Sony product. The full name of the product is PlayStation Vita. The product is registered with a trademark. So far there are only two models, 1000 and 2000. Any other brand of equipment, which calls itself PSV, is fake and shoddy.

Secondly, let's talk about two handhelds in the question. The first one is PlayStation Vita, which is Sony's own product. You can play all the games on this platform, and these games rarely appear on mobile platforms, including Android and ios, but the games need to be purchased separately.

The second is a handheld game machine running Android, which can only run games under Android. To put it bluntly, it is an Android phone with a handle. You can't play games on PSV. Many Android games don't need a handle, or it is difficult to be compatible with the handle on this machine.

It's simple. As for how to choose mainly depends on the demand, some core players who like games will choose PSV, but it is true that games are more expensive. If you really want to play some casual games to kill time, an Android phone is enough, so you don't need to buy this device.
