Security-wise, they're about the same. The only real difference is that
Unity will be more actively supported than Gnome-shell on Ubuntu. They
share so much in the backend, though, that you're unlikely to find that
there's any waiting security fixes for gnome-shell.

If you're looking to go down that route, it would be good to clarify
which bit's which. Gnome 3 is a desktop environment, which provides a
bunch of libraries for doing things like drawing windows (hence most
apps looking similar and behaving in similar ways), automounting of
devices and other handy tools.

On top of this is run a 'shell', which is the bit you actually see.
That's what dictates where the menus go, and precisely what those
libraries do when applications use them. There are two common options
for this on Ubuntu - Unity and Gnome-shell.

Gnome-shell is what most people term 'Gnome 3' because, in the absence
of Unity, they're relatively synonymous. But if you try to install
Gnome3 you will find you've already got it because of Unity - what you
need is just the gnome-shell component if that's what you want to try.

That said, it's worth noting that the standard Gnome-shell session
doesn't have a bar at the bottom either. There is a gnome-fallback
which looks a bit more like the Gnome of old, but that has a fairly
limited expected life.
