Some examples work on some cars with some setups. When they work, they really do make a visible difference.

But that said I'm far from convinced that this applies to all cab forward shells, or even that the better examples are always a good idea - its really more of a tuning tool and I'm sure there are places a traditional cab is more suitable.

In the main its a fashion thing though. Lots of cab forward shells appearing that probably aren't as aero-tuned as something like a Proline Bulldog so most likely don't make the difference people claim.
