Oracle is a RDBMS software, means, Oracle holds the database (data created/updated using application). Visual basic is tool to develop applications & this is from Microsoft. You can write programs/application to access the data from the RDBMS like Oracle, Microsoft SQL Server, etc. Since the functionality differs (i.e. Oracle = RDBMS & Visual basic =Application development Tool) for the two software applications, "which one is the best" can not be answered.
Oracle is no more complex than any other RDBMS, such as MySQL or PostgreSQL. It has some unique features not found in other RDBMS', and is missing some features that may be found in other systems. Knowing "standard SQL" will give a basic level of knowledge needed to use Oracle, and then, as with all other RDBMS software, some additional learning will be required to take advantage of advanced features.
Oracle is an RDBMS aka Relational Database Management System and SQL (Structured Query Language) is a programming language.
