The evdev and SDL backends suffer from impedence mismatch and they cannot work identically to hidraw on every possible device. You should use hidraw with your device, and every time it is supported, and evdev / SDL for every other devices where it's not.

Then making sure evdev / SDL works best for devices without the hidraw alternative is more important than making all the backends work similarly for devices which can already be used with hidraw.
