What Carnival cruise is better to the Mexican Riviera?

I took a similar cruise on NCL a couple of years ago. The ports we stopped in were Acapulco, Ixtapa/Zihuatanejo, Puerto Vallerta and Cabo San Lucas. I liked Cabo the best of all of the ports we stopped at and probably Ixtapa/Zihuatanejo was my second favorite. I've included a link to a website with photos of activities and info from our cruise to Mexico in case it will help you decide.
