Although I haven't used the LC, my reasoning for going with the Edge was as follows.
1. No need to worry about centering the pad. The adaptor and pad do it for you.
2. Pad changes in literally 2 seconds. Push the release button in the center of the adaptor through the hole in the pad and it pops off.
3. No backing plate to ever worry about hitting the paint/panel (I'm a noob so it crossed my mind).
4. Two sided pad versus 1 sided pad= better value
5. Comparatively priced when you consider you are getting 2 pads (in one Edge pad) for a lesser price than 2 LC pads.
6. No backing plate to ever replace.
Hope that helped.
