In which technical aspect are they more advanced than the choices made in the first post?
The sheer size of Driveclub's environments alone make what they accomplished extremely impressive, with some of the tracks I believe consisting of nearly a million trees (Edit: Up to 1.2 million trees on one track). Everything seen is fully modeled in 3D and the lighting/cloud/weather system is the most impressive I've witnessed. Of course it's a bit of apples to oranges with Unity, considering one's a fully realized city sandbox and another is a track racer, but I was just more blown away by what Driveclub offered. I can see why some people would pick Unity, though. It's certainly no slouch.
Some of what Driveclub does is listed here:
