I don't think borrowing someone else's configuration will help, at least never for me. There's too many variables like are you willing to use macros and to what degree, keyboard/mouse/controller keys, etc. It's mostly what's most comfortable to you.

I personally wish we could just take each individual hot key block and arrange them separately instead of as a full bar. I need visual separation between sets of keys so I can more easily tell at a glance what skills i should or can press and the corresponding keys instead of seeing three rows of colorful buttons that all blend together in my peripheral vision.
