@Sheherezade there is not much difference between RD and PD. If you want to use for yourself I suggest you to go with RD. RD uses you device goggle play configuration and only make the patch for your device. In this case you don't need any additional proxy or anything. RD is slightly safer than PS if you only want the game for you.
On the other hand PS patch is for Sharing that uses proxy server.
