SWCC is more about the direction China took under Deng, which can be anything from praise to neutral to derisive depending on what someone thinks of Deng and that direction (I think it's worked out reasonably well, personally). It is heavily drawn from the direction under Mao, and by necessity cites Mao, so they aren't purely distinct but I would say that means learning about SWCC should involve reading Mao but you can read Mao without SWCC. e.g., the Black Panthers were inspired by Mao's writings and built on them, but did not build on Deng / SWCC.
