The SCA ones have a higher tolerance then the SCU SM ones which have a higher tolerance then the MM ones. The MM ones will work with a plastic sleeve where the APC ones need a ceramic sleeve. TLDR; green ones will work with everything. Blue ones mostly work with APC but sometimes not. Brown ones can be pretty crappy.
