The ease of use of the product and the ability to integrate with almost every possible DB Engine, along with the UX and look 'n feel are great. Also it has great functionality like ER Diagramming and is a great tool for all round database interactions. Also the incremental fetch is a great functionality. It will provide most JDBC drivers to connect to most DB engines and download automatically to use on a new connection.

I love how easy it is to switch between databases and servers, even across multiple languages! Setting up servers is intuitive and easy. The keyboard shortcuts are nice, so I can easily query multiple items without every taking my hands off the keyboard. The interface that comes up makes adding rows to a table extremely simple! Furthermore, they even have automatic query generation for simpler queries so this isn't just for developers but also for operations. The syntax highlighting is nice as well, making it much simpler to read queries because words change color based on context. The errors are easy to understand and help you figure out how to fix your broken queries!

It is a very robust application, allowing me to easily look at our Postgres database, as well as look at other sources. One really great feature that is often used is the ability to open CSV files and treat them as databases as well.
