Hi Cbgomez2011 and welcome to MySwissAlps!
The best rail pass for you will depend on your final itinerary.
To know which pass is the best for your specific itinerary you need to plan out all trips you will make (train, bus, boat, cable car) and compare the prices for regular tickets to the rail pass price (and which routes/mountains are free or discounted). Once you have that information you can read our page here on how to choose the best rail pass. There is a spreadsheet there to help with the math. :)
