One of the things from those is the newer accepts bigger smartphones, also you should see the accessories among them, one or two only brings you the Controller, the other two controllers others a new controller NFC compatible.
It's important you check the size of your smartphone screen and the cardboard compatibility first, then if you really need more than one controller (I don't suggest you to opt for those with 4 controllers).
Another thing, there are another options to buy, I always recommend to look for more than one store, try maybe gearbest.com, tabletexpress.com and I know there are a few more with worldwide shipping.
If you budget is truly high and you have a VR Ready computer I will recommend you the ViVE.
If you already have a PS4 you may prefer the PSVR.
I hope I helped you.
