I have the
Meg's 5" bp for the PC and when I had to get a rotary backing plate, I ended up getting the LC flexible bp. I can't tell you if the LC is any better because I've yet to use it enough to give you my opinion, but the reason for the switch was the fact that I hated how the Meg's backing plate cuts into my pads. It's a hard plastic with a sharp edge and pretty must most of my Meg's pads are ruined because the bp cuts into the foam. It also didn't help with the fact that the Meg's pad itself does not have a full velcro backing.
