I'm a pretty big fan of his so this isn't meant as a criticism, but I think his stand up delivery/style is often reminiscent of Louis C.K., and his sense of humor on the podcast sometimes reminds me of Kenny Powers from Eastbound & Down. I'm sure he'd admit they're both big influences on him, so it's whatever.
And yes, he admittedly said some unsavory words in that podcast clip that got him cancelled, but the bit genuinely was basically a satire mocking how white people used to think of asian people as less than human.
Maybe an unpopular opinion, but tbh I only found like half of the G&K sketches I saw funny.
