Ranked in these QuestionsQuestion Ranking
Pro De facto standard client for SSH, Telnet and Rlogin on Windows
PuTTY is one of the oldest and most popular clients. It has earned the trust of a great number of users over a long period by being reliable, offering useful features and helpful support. It got into the 15 Essential Open Source Tools for Windows Admins list by InfoWorld.
Pro Can be used on any Windows computer, even without admin rights
Pro Source code available
Full source available. Compile and modify it yourself.
Pro Lightweight and portable
Doesn't require much resources (memory and hard-disk). Can even be run on a system by just downloading without install.
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.
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 Customizable UI to allow for maximum net screen size up to fullscreen
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 Open source
Open source and hosted on Github.
Con Can not save passwords
Anyway, you can use "PuTTYgen" to generate a key pair, then use "Pageant" to do a password-less SSH remote login.
Con Lacks features
It is JUST an SSH client. There are many other options with built in X-servers, Multitabbing, etc.
Con Ugly design, too simple
Looks very dated. Does the basic functions very well, but not much more.
Con Only one session
Cannot open a second session in the same window.
Con No global settings
If you want to change a setting for all your connections, you'd have to do it individually.
Con Organizing sessions
Does not have features for organizing session connections (like folders). If you have 5-10 connections that's fine. But if there are 30-50 connections - that becomes a nightmare.
Con Tedious logging/tracing
Its tedious to set up logging and tracing (e.g. for serial connections).
Con No login scripting
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.
