I'm not sure that I would describe the route as easier, as the both start, and end, at about the same respective altitudes.
I *will* say, though, that I think the South Fork trail is much less used, feels more wilderness-y and remote. You will likely have the lakes to yourself, as well as the fish! The only hard part of the trail is the last 1/4 or so mile just before you get to the first lake, it is a steep, switchbacky section. Not really hard, just slower. However, up to that, it is pretty flat, and quite a bit runs next to the stream, with camping opportunities, if you are so inclined.
