Which is better for (i) investment and (ii) living? Your views are invited please.
My opinion:
At the moment, for investment DHA-II is better but for living Enclave I is better due to proximity to Islamabad and scenery.
However, if they really build Islamabad Highway into some sort of a signal-free superhighway up to Rawat on which you can whiz by in your car at 100-120 km/hr, then most likely DHA II will be better also for living. This is because in that case the ease of straight and fast driving will tilt the balance of comfortable living in favour of DHA-II against Enclave.
Comfort includes ease of commute as one of the primary considerations.
