Compiling vs pre-compiled packages

[fardoche <fardoche99 videotron ca>]

If I got both GNOME pre-compiled packages for my platform and I
can also compile the sources without too much problem, wich is the best?

I mean, if I compile myselft GNOME for my machine, will it run faster
and be more stable, or it is kind of a waste of time when you can have
the latest GNOME packages for your platform?

Thanks!
