So far I've only ever been rejected for Affin. Quite siao...when I apply for car loan they die die wanna give me a CC, I had to threaten report to BNM only then they remove it. Around a year later I wanted to apply for Affin Duo, they reject, and even reject after appeal. Got ample DSR, no issue with any repayment. Screw them lah.

SCB and Citibank probably the easiest (have apply/cancel these multiple times over the years). Others that I didn't face any issue with - CIMB, HLB, RHB, HSBC.

Never applied - AmBank, Public, Alliance
