Has a great variety of themes which transfers pretty ugly application into a great looking one.

Anyone who uses the views function will appreciate Adminer better. You can click on a view and edit to change the view. In phpMyAdmin, you can edit a view, but it's not easy or intuitive. SQL Buddy doesn't have any way of doing this.

You can use all browser features like "Find in page" (the whole page), auto fill, password management etc.

Entering multiple different SELECT/WHERE/SORT conditions is easy

It supports several database management systems (Postgres, SQLite, Oracle, MS SQL and of course MySQL)

The installation and Adminer itself only requires a single PHP file. Once it's uploaded you can log in and start using it.
