Since the introduction of the Theme Customizer which are most people using in WP themes? An options panel, the customizer, or a combination of both?
You simply can’t fit all options in Theme Customizer, I use it only for visual changes (color pickers etc), all other options still are in Options Panel. So combination of both.
I’m going for both in the theme that i’m working at now.. I think it’s the best route:
Have layout, colors & fonts in the Theme Customizer, since it’s a lot better to “live edit” these kinds of properties in the theme..
Have all the other heavy options(analytics, custom css, blog & folio settings, etc.) in the Theme Options, since they are not visual properties that should be in the tc..
