Which of the above should I use. Please let me know with respect to the following aspects:

• Efficiency
• Licensing (are both free? )
• Ease of development
• Compatibility with .NET datatypes etc.

Answer 1

the only way you should go is the ODP.NET, the OracleClient has been deprecated and will not be supported any longer in future versions of the .NET Framework.

check here: Microsoft OracleClient Deprecated

Edit: from the linked article:

Oracle's free Oracle Data Provider for .NET (ODP.NET)

ODP.NET 11g is compatbile with all versions of Oracle Database back to 9.2, and multiple versions can coexist in a single OS
