I'm motivated to update my emacs-24 and emacs-vcs USE to address the known bug with emacs daemon, GTK and X disconnects:
Code:
Your current Emacs is compiled with GTK+. There is a long-standing
bug in GTK+ that prevents Emacs from recovering from X disconnects:
<http://bugzilla.gnome.org/show_bug.cgi?id=85715>
If you run Emacs as a daemon, then it is strongly recommended that
you compile it with the Lucid toolkit, i.e. with USE="Xaw3d -gtk".

I've run into this on many occasions, but X restarts are infrequent enough that I've just lived with the risk.

In what areas would graphical or capability differences be noticed with +Xaw3d -gtk?

I use Emacs full screen, with no menu or other window decoration. I never use GUI windows for file selection, etc. The only place I regularly see a widget is when shift-clicking to change font size in a frame (I can never remember the command to do that), and the in-buffer buttons on buffers like customize, etc.

Is the move away from GTK and GTK3 going to change the user experience other than widgets?
Code:
$ sudo emerge emacs emacs-vcs -pv
[ebuild   R    ] app-editors/emacs-24.1  USE="X alsa dbus gif gnutls gpm gtk gtk3 imagemagick jpeg
libxml2 png sound svg tiff xft xpm -Xaw3d (-aqua) -athena -games -gconf -gsettings -gzip-el -hesiod
-kerberos -livecd -m17n-lib -motif -pax_kernel (-selinux) -source -toolkit-scroll-bars -wide-int" 0 kB
[ebuild   R   #] app-editors/emacs-vcs-24.1.9999-r1  USE="X alsa dbus gif gnutls gpm gtk gtk3
imagemagick jpeg libxml2 png sound svg tiff xft xpm -Xaw3d -athena -games -gconf -gsettings
-gzip-el -hesiod -kerberos -m17n-lib -motif -pax_kernel (-selinux) -source -toolkit-scroll-bars
-wide-int" 0 kB

Thanks for any tips.

tbh I don't expect this will help much because I'm not entirely sure but I've always built emacs myself and only since I think 22 or maybe 21 did I start using './configure ... --with-x-toolkit=gtk'; until then I had always used './configure ... --with-x-toolkit=athena' (which enables Xaw3d).

iirc the only real difference was visual in that the menubar/menus and scrollbar/arrows use the color/gradient effects of my gtk desktop theme which makes them stand out a bit more from buffer bg. I suspect perhaps modeline could be affected too but I think I'm overriding that somewhere (personal preference). with "athena" I think the menubar/menus at least picked up their color from ~/.Xdefaults 'emacs*Background' (how I did it anyway) so the affect made it more or less seamless visually.

so if there's some functionality aspect to using/not using gtk it's not something I was aware of or recall taking note of once I made the change.
