From Oracle's documentation states that the use of  OCI driver is for maximum performance and the Thin driver is for maximum portability.

OCI versus Thin driver timings (in milliseconds)

It clear for us that  Thin driver outperforms the OCI driver for every type of operation except executions of CallableStatement objects.The Thin driver has been well-tuned by Oracle's JDBC development team to perform better than its OCI counterpart
