The only difference between OFRs and LFRs is that LFRs are licensed, ie, they're copies. OFR is Original Floyd Rose, just like you have Original Gibsons, and then Edwards etc.
Most Floyd Rose copies are made from cheap metals, where the knife edge dies much quicker, and then you need to replace them. Other LFRs have different mechanisms, etc, but essentially they're all variants of the original OFR.
Some LFRs are shitee. Some are great.
But the OFR beats them all imo.
