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 Open source
Open source and hosted on Github.
Pro VT220 emulation

Pro Buttons bar
SecureCRT while not free has the ability to make common commands in to button for faster command processing. Commands like: exit, clear, :wq!, ls -lha and the etc.
Pro Scriptable via Python API
Has a Python API to control most aspects of the terminal and sessions. Scripts can be bound to buttons, menu items, and keyboard shortcuts.
Pro Puts emphasis on security
SecureCRT has strong data encryption and secure authentication through the support of password and public keys.
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 free
Paid product. Some nice additional Cygwin type features and server version are integrated, but for most users the feature set probably does add enough value for a paid only client.
