If you are looking for a MySQL admin tool that isn't phpMyAdmin, Sequel Pro may just fit the bill. A community project that in the process of expanding beyond MySQL to other DBMSs like PostgresSQL, MS SQL Server, it looks like it has a lot of potential and decent management of the project. The UI design is somewhat lacking and is missing the ability to compare/sync two databases. Also missing is the ability to export a database and obfuscate production data for use as test data.
SQLyog MySQL GUI is the most powerful MySQL Manager and MySQL Admin Tool, combining the features of MySQL Query Browser, phpMyAdmin and various other MySQL Front Ends and MySQL Clients in a single intuitive interface.
