For those of you who have forward facing bike mounted cameras (not helmet cams) do you mount them to the frame or to the handlebars?

Does it matter?

I figured the frame would be a more stable option, but it's a little harder to do. The handlebars move more so I'm wondering if you get too much wobble and shaking.

Or am I overthinking this and is doesn't really matter as long as the camera is aimed forward?
