Accessing Oracle 10g (and higher) from .Net 2.0?

I have yet to find a good comparison of technologies for accessing Oracle from .Net applications...

Are there significant diffe开发者_运维技巧rences between Microsoft's System.Data.OracleClient provider and Oracle's Oracle.DataAccess.Client? My current company is using both because they couldn't figure out how to return a cursor from an oracle function using System.Data.OracleClient. (I fixed that for them, so that is not a factor) For dynamic sql queries, they prefer to use System.Data.OracleClient as they feel that Oracle.DataAccess.Client is "picky" and causes other problems in general.

Edit: Deprecation of the System.Data.OracleClient types is not a concern

Other than Deprecation of System.Data.OracleClient, are there significant reasons to lean one way or the other for new development?

Would a comparison grid between Oracle ODP.net and Microsoft Oracle Client help?
