[Not trying to start a war, just posting my observations from trying
 both kicad and gschem...]

For me the "deal killer" with kicad is that it has no way to handle
multiple instantiations of subsheets.  As a result I'm using gschem
for some stuff I'm working on.  gschem isn't particularly pretty, and
there are some things I'd like to fix in the UI, but it has a very
active user/developer community, mailing list, and code that's easy to
get to do what you want (modulo knowing scheme ;))

Kicad does handle multiple heterogeneous sub-components per package
much better than gschem currently does.  For me, the lack of fully
general support for subsheets was the deciding factor.
