SAP FICO ?

Hello Everyone    

I have 9+ year experience in ERP field and very much comfortable in all areas like Finance, Operations etc.My experience in Sage ERP and other which we developed in our company by using global concept of any ERP system which is successfully running in many clients.

Now, I want to move in big brand like SAP but I am confused reason that, I have done my graduate in commerce (Distance Learning) and PGDBM in Finance (Distance Learning). I have following questions:

1. Which ERP finance module is best SAP or Oracle?
2. Should, I go for SAP FICO course with Distance Education? If, Yes then Can, I get job opportunity in MNC level.
3. Is certification is must for better career?

Thanks
