This actually depends on your overall system configuration. I've tried both and found the Hardware Drivers
applet (a.k.a Restricted Driver Installer) to be more preferable
. On some machines, however, EnvyNG
seems to do a better job.

Yes. One thing that I remember is EnvyNG
also installs nvidia-xconfig
which then will give you access to Nvidia X Server Settings
(via Control Center). It gives you more options to customize several aspects, such as Anti-aliasing level, Anisotropic filtering level, just to name a few. If you use Hardware Drivers
applet to install the driver for your graphics card, you'll have to install
those additional components manually
through Synaptic. Additionally, I reckon switching display resolutions can be a tough job using either one on some machines. Thus, as Husse said, you'll have to try both to figure out which one suits your taste best. Hope that helps.
