If you run the 419 Arca lock clamp then their proprietary rail with the scalloped edges is essential. You can take the pins out of the clamp, but that defeats the purpose of the clamp/scallops to lock everything in place.
If you're running a standard arca swiss clamp, then the Area 419 rail isn't essential.
Otherwise, (subjective) milled aluminum is milled aluminum.
I put Area 419 rails and clamps on all my rifles / bipods for no brain damage compatibility. Grab one and go. Never get to the range or out in the field and have an "oh shit, I grabbed the wrong one" moment.
