Both SDI and PADI adhere to the RTSC (Recreational SCUBA Training Council) standards. This means both agencies are required to have the same content in their corresponding courses. Is one better than the other? I don't think so. Both an open water certification from SDI and an open water certification from PADI are recognized worldwide as an open water certification. Each agency recognizes the others certifications as well. This means PADI views an open water certification from SDI as being equal to a PADI Open water certification and vice-versa. The only difference between the two is that SDI requires the use of dive computers (which are awesome to use) and SDI's materials are less expensive. This is why SDI courses are less expensive even though they contain the same content mandated by the RSTC.
