Pros
Pro Free
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 Comes with bash and zsh out of the box
Babun comes with both bash and zsh out of the box. This gives both beginners and advanced users the choice of which shell to run.
Pro Comes with a package manager
Babun come with a package manager called Pact, which is an extremely simple yet powerful package manager similar to apt-get
or yum
for Linux.
Pro Easy access to powerful zsh features through integrated oh-my-zsh
Oh-my-zsh is a dead simple configuration and management for zsh (which is a pretty powerful shell), allowing even first time users to take advantage of the most powerful features it offers.
Pro Extends Cygwin functionality
Babun is built on top of Cygwin, meaning that Unix or Linux applications can be compiled and run on a Windows operating system from within a Linux-like interface.
Pro Decent, out-of-the-box remoting to Unix and others
256 color xterm is simple, but many programs simply do it wrong. Babun uses well-established command-line programs that do it right, and which then wrap them in a nicely themed package.
Cons
Con Only one session per window
Cannot open a second session in the same window (you need multiple windows).
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 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 Dead project
Babun is not maintained and uses an old version of Cygwin from 2015.
Con Cannot exit node.js programs
When trying to exit a node program using Ctrl-C, the process doesn't actually exit.
Con No tabs
Babun has no support for tabs.
Con No spinner when installing packages with gems or npm
Con Does not work with Ansible
Executing Ansible modules (which helps configure and manage computers that combine multi-node software deployment) causes errors to arise.
