What is the difference between Amazon Aurora and Amazon RDS

[PeleCorya]

I am looking for a mysql / postgresql type data store for my application. What is the difference between Aurora and RDS on AWS?

Is it better to use one over the other?
Are there any cost differences?

Amazon Aurora is a fully managed MySQL- and PostgreSQL-compatible relational database built for the cloud that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases.
Amazon RDS (Relational Database Service) is a managed SQL database service a relational database in cloud which makes it easy to provision, setup, patching, and backups. It supports Aurora, MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle database engines.

RDS is compatible with MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle.

Aurora offers higher availability and better durability than RDS, due to its unique storage model, and ability to perform continuous backups and restore with a very low RPO (recovery point objective).
