Which version of Oracle are you connecting too? Depending upon which version of Oracle you have will make a difference on which ODBC driver you want to use. Everything may look fine now - but I've had significant issues with unexpected results if you're using certain ODBC drivers with some version of Oracle . One big issue I had was getting data that was pulled from a DBLINK in oracle - one ODBC driver works whereas another one does not...plus other things like truncated character strings and such - really odd things can happen.
