One is made by Microsoft and one is made by Oracle. One clusters the entire O/S (including all applciations on it as far as I know, but I am not an expert on Microsoft Clustering) and the other clusters only an Oracle database instance, even if there are other applications running on the server(s). Also, for Oracle RAC, you must have some kind of shared disk storage (usually a NAS or a SAN) that will actually hold the database files. For Microsoft Clustering, I don't know if any exernal, shared disk storage is required, or not.
