Advise needed please // PMP from scratch

Dear gents,

I have just started preparing for PMP exam from scratch, some of my friends suggested that i should go through Rita and PMBOK but due to my busy schedule i really don't have enough time to go through both. Could you please recommend which one of this tow is the best option for preparation and go through in my current situation knowing that i have more than 5 years of experience as project coordinator.

Thanks a lot in advance.
