Pros
Pro You can run tabbed sessions
Dynamic placement of tabs side-by-side vertically or horizontally (similar to IDEs like Eclipse/Visual Studio). This is an upgrade of the original PuTTY, which lacks this feature.
Pro PuTTY configuration reachable and adjustable
Since it uses PuTTY underneath you can create and configure profiles/sessions there which you can reuse in SuperPuTTY and apply to connection in any fashion you like.
Pro Easy shortcut-driven navigation
By setting up certain shortcuts you can quickly bring up your sessions, select one by typing out the first letters, return-selecting it and cycle through your tabs.

Open source and hosted on Github.

Cons
Con You still need to install PuTTY first
SuperPuTTY is a wrapper available for PuTTY, not a standalone program, therefore you need to have a PuTTY installation before you can use SuperPuTTY.
Con Not completely freeware
If you use MobaXterm at work, they hope you will pay for it. This isn't horrifying, but it's not providing any new features in Linux to warrant the outlay. Its integration with Putty in Windows as an X client may make it worth the funds.
Con Split screen prevents tabbed mode
If you split a screen within a tab, you have to go back to single screen before you can switch to another tab.
Con Can have some performance issues
MobaXterm can have some occasional performance issues. These happen rarely but it's worth mentioning that they exist, especially since this is a paid tool.
