Pro Can store login credentials
Ability to store passwords/passphrases locally.
Pro Source Code Available
Source code is available so you could modify or review changes.
Pro Startup sessions
Support start-up sessions which allow you to specify the window/tab layout, working directories, and programs to run on startup.

OpenSSH is the reference for all ssh clients.
Pro It's extremely easy to get running
All you have to do is go to the Microsoft store, choose a Linux distro you like, and install the client for free.
Pro Excellent way for Windows users to learn Linux
It is much easier and more convenient than dealing with a dual boot Linux installation.
Con No centralized configuration
Each session holds its own configuration of all features. This means that if one wants to change a configuration common to all sessions (say, the terminal font), it has to be changed in each stored session separately.
A better solution would be to have a default configuration and store only the changed elements for each session (both configurations would be merged, with e priority on the specific one).
Con No tabbed sessions.
No built in support for tabbed sessions. Requires an add on.
Con Graphical problems
For example running Midnight commander (MC) makes terminal blinking.
Con Crontab and other background jobs don't work properly
Crontab only runs on ROOT, and it needs Windows to stay open. If you close it, you will kill the crontab. Some background jobs don't run on Windows WSL.
Con Command line editing does not work properly
Overrides chars instead of inserting them... depending on position and moon phase?
Con Does not install on PC virtual machines
Con Forces window to a certain size
Any other SSH client will render the remote server at whatever size the local client window is. The built-in SSH client on Windows, however, forces you to use a standard size, and it's small enough to cause problems.
Con Windows' SSH key agent service is broken
Attempting to use the built-in ssh-agent provided with Windows will cause errors and authentication failures due to an incompatibility between Windows' ssh-agent and OpenSSH on remote systems.
Con Cut & paste works like the Windows prompt
Older versions of the Windows Command Prompt select text in a rectangular region of the console, rather than starting at a character position and selecting forward or backward along with the logical flow of text. To copy a sentence, for example, would require that you select all content in the two lines that contain the sentence, then trim what isn't needed, rather than just selecting the sentence. In later versions of Windows 10, this may not be an issue, as the cut-and-paste behavior has changed.
