Most chains sold today have some kick-back reducive features - the RSC has the big, wide, "bullet-chaped" rakers, same as the Oregon LG.
The Oregon LP has a small ramp on on the drivers, directly in front of the rakers, and the RSC3 combine both, so I suspect it isn't a very good chain,
the worst kind is the chain are the ones with the big bumpers on the tie-straps, like Stihl RM2, PM1, Oregon SL and VG, etc...
The most effective chain sold today probably is the Stihl RSK, as it has none of the "features" mentioned above, just some rather slim rakers, like the LP, but without the ramps.
