I would prioritize CFAI’s qbank since they set the exam, seems like they are the middleground in terms of difficulty. Then would do some MM, and if I have time, Kaplan last. Rather be surprised that it is too easy, than too tricky in the real exams!
May be worth checking out other providers as well that are offer free L1 question banks like Uworld, heard that you can customize difficulty in that and may be useful to replace that over Kaplan if you run out of questions.
