SQLyog MySQL GUI is the most powerful MySQL manager and admin tool,
combining the features of MySQL Query Browser, Administrator,
phpMyAdmin and other MySQL Front Ends and MySQL GUI tools in a
single intuitive interface.
MONyog MySQL Monitor and Advisor is a "MySQL DBA in a box" that helps
MySQL DBAs manage more MySQL servers, tune their current MySQL servers
and fix problems with their MySQL database applications.
I have used MySQL Enterprise Monitor for a year and a half, and although some believe its a superior product, its 5K per server per year for the Enterprise version. I just started using MONyog a month ago, and purchased it today.
I bought the Unlimited Pack and that is a perpetual license for an unlimited amount of servers. It gives me all the monitoring I need and without an agent installed on the MySQL server. That makes the sys-admins I work with very happy.
My prefered feature is the log analyzer. It makes analysing the slow-query-log and the general-log really easy and efficient.
Cool product, check it out if you can.

As a developer, SQLyog Enterprise has been one of my essential tools for 7 years now and has never let me down. The Powertools are the icing on the cake and set it above all other DB administration tools I've used.
