Toad is maintained by Dell and has great community support.
Toad is free to use.
Pro Clean and pretty UI/UX
The default color is dark and comfortable for the eyes.
Pro Multiple Query Tabs!
The multi-tab and multi-SQL-runs are great. It's always good to be able to compare results in one window instead of having to go through and re-run stuff.
Pro Fast Auto-complete
Pro Multiple Databases
They only support 2 at the moment (MySQL and MariaDB) but their social site says they'll be updating with more DBMSes in the near future which is pretty nice because I hate learning new GUIs~
Not sure about Linux but it works on Windows and Mac just fine!
Con Fewer features
Still some more features are required to add. Other than that its perfectly fine.
Con No built-in SSH tunneling
Toad currently doesn't provide built-in SSH tunneling.
Con Requires creating an account
Requiring an account is rare on SQL IDEs...
