Hi Que,
Yes and Yes. Let me qualify the second point ...
* You're fighting against multiple bandits, or even one bandit - you can look at the bandit, then check your wingie's six, then look back at the bandit. No remembering keypresses and wondering which bandit you're padlocking, just turn your head.
* You're cruising along over the FLOT, and have a couple of CBUs/GBUs left. You lean forward and out to see under the 'plane without having to bank. (note, this is only possible in OpenFalcon and FreeFalcon).
* You're landing, and instead of being vectored for a straight-in approach, you have to orbit for spacing then join on the base leg of the circuit (pattern?). You can look to see your orientation to and distance from the runway, then look back at where you're going. You can even look out for traffic that isn't directly ahead of you.
This is why I find 6DOF (where available) far more immersive.
