It's going to be really hard answering this without more info. But what you can do is to analyse your trouble spots: what are you trying to conceal, pimples or dicolourations and choose from there. I'm not too sure, but I think Coverette is more pigmented than their conceal-all wheel.
Personally, I'd advise most WOCs to get a salmon or orange corrector from Ben nye (like Mellow orange medium or deep or Tattoo cover 3 or 4), bcos some WOCs suffer from ashiness around the jawline/upper lip or purply-blue discolourations under the eye.
The best answer would be to share what you want to cover, so more people can weigh in on this and check youtube for descriptions of the diff. Ben nye concealers/correctors. hth.
