...between a low profile Original Floyd Rose and a regular Original Floyd Rose, other than the slightly different looks and comfort, do they have same performance, consistency, and quality?

Performance depends on the body routing, for most low profile, the cavity needs to be a bit deeper than normal in order for the up-pull to have good range. In terms of material, so far IMHO, the OFR > fr pro, low profile fr, etc etc.

I've heard some complaints about the FR Pro/low profile.
