For PvP I almost always (exception are close air distance long ground maps which I might go for a fast VR) go for 3 gates + Council.
The council let's you have a lot of versatility to adapt to your opponent, blink will usually be enough to fend of early void rays, chargelots are very good against immortals or heavy stalkers armies.
I usually get blink first unless I have a very good reason to get charge.
From there you will see the fact that you have these 2 upgrades (potentially) + 3 gates make you strong enough to counter any 1 base army, blink stalkers will be good against void rays (unless he makes ton and get them charged up, you must win the game before that since he will have a weak army, if you fear a very big number of void rays, try to see the surround of your base to be there before they are charged up and either get phoenix or your own void rays (on top of your stalkers)). Charge lots will be good against blink stalkers (backed up by your own) and immortals.
Your opponent then won't be able to go heavy HT or colossus with one base, so you either expand yourself or try to finish him right there.
You must be aware of DTs, a good follow up then is to add one robo for observers it will help your blink stalkers and fend of DTs. You can also go forge to defend against DT. But go forge if you expand not on one base (and add sentries because it will cost a lot of minerals).
From the council you have also the option of going DT yourself, this is a very viable option if your opponent goes void rays or blink. Do not neglect the use of DTs later in the game also, they are useful to really harass some bad expansions.
