With your pc, definitely go for vive or oculus since they allow for room scale.
PS VR is limited by both the camera and the ps move controllers. With only 1 camera tracking the move controllers, tracking will be lost the moment they are out of view (including when you're obstructing the camera) so you normally limited to games that focused more on the front to 180 degrees. Since you dont have analog sticks on the move, you either get awkward work arounds to move around or games like upcoming Skyrim that disable normal movement when using the move.
Vive/oculus allow for room scale vr, so you can pick things off the ground, turn around etc without losing tracking of the controllers. Theres also a bigger library of games as you can play steam vr and oculus games no matter which headset you buy. On top of that, mods are available for non vr games like alien isolation so theres a bigger range of opportunities for vr whether or not devs officially support it or not.
Vive uses a lighthouse system that do not need to be wired to the pc so thats a big advantage over oculus if you want less wires (with oculus, for full tracking you'll need one sensor positioned at the back of the play space connected by a usb+extension cable. All the headsets will have wires though that connect directly to the headset so you won't be able to avoid the wires that are by your feet/legs. Some people use a ceiling set up to hold the wires if they bother you too much. TPcast is definately expensive (especially when it doesnt allow mic support from the headset).
Your pc will be able to play vr games that look and perform better than the ps4 pro too.
Why to choose PS VR:
- exclusive ps4 vr games
- its the most comfortable of the big 3 headsets
- Probably the easiest to set up
- least expensive overall
Why to choose Oculus or Vive:
- Perfect tracking + room scale (vive is perfect out of the box, oculus requires a 3rd sensor)
- Controllers are leagues above ps move (Oculus is the best right now with touch but Steam Knuckles controllers will come out soon that are a step above oculus touch)
- Exclusive pc games (both headsets can play oculus and steam vr games). Oculus seem to be pushing for an exclusive ps vr game almost every month.
- Better graphics, performance etc
