Hey there, i will help you out with this,USMLE has multiples resources that you can prepare for , like KAPLAN,BECKER,PATHOMA,DIT,PICMONICS,SKETCHY MICRO PHARM,LECTURIO,AMBOSS,BOARD AND BEYOND,GOLIJAN ,OSMOSIS,FIRECRACKER and qbanks like UWORLD, QMAX,KAPLAN and books like BRS ,HI yield and many more.basically its up to u to choose what u like or want,Like different people prefer different brands.it basically comes to individual preference.but always start and end with NBME to assess yourself and also use FIRST AID,and UWORLD  and PATHOMA as your core resources. good luck buddy
