Best reviewed Case Interview Prep Material?

So I’ll be applying for an MBB internship next cycle (Undergrad, LatAm)

I was wondering which Case Prep materials were considered among the best. I already got Victor Cheng’s LOMS and Case Interview Secrets, and was looking for another program to complement them.

Rocketbook’s drills also seem pretty great (And relatively cheap). I don’t want to throw money at my screen and pretend that’s somehow gonna make me more prepared. There’s no way I manage to fully use any particular program’s features if I end up with 4+, instead of really dedicating myself to 1-2.

I was looking into MConsultingPrep’s material, as well as WSO’s package (Which seems pretty complete). While Victor’s material is highly regarded, I’ve been unable to find many reviews regarding either WSO or MCP.

What is everyone’s thoughts on these specific programs? I’ve narrowed it down to WSO and MCP, but would like to know if anyone here has had experience with either.

Cheers.
