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 Supports splitting tabs into views
In ConsoleZ, the user can split a tab into different views either horizontally or vertically.

Pro Fullscreen support
ConsoleZ can be opened in fullscreen.
Pro Small, portable installation
Install to OneDrive/Dropbox/Google Drive and your setting will be consistent everywhere.
Pro Supports typographic ligatures
Typographic ligatures occur when there are two or more letters joined as a single glyph, such as "æ".
Pro Easy transition from Console2
Being a fork of Console2, ConsoleZ is fully compatible. It even recognizes existing Console2 config files, making the transition easier.

Pro Input sent to one view can be sent to all
ConsoleZ allows for grouping of open views (panes) so that if an input is sent to one of them, it can be sent to all views grouped with it automatically.
Pro High DPI
This means that the display screen in ConsoleZ is sharp.

Pro Drop-down animation support
ConsoleZ can be used as a drop-down terminal inspired by the famous Quake terminal. Once opened, it can be toggled with a key of the user's choice. This makes it easier to have access to it from any window instead of having to cycle through all open applications.

Pro Localization support
ConsoleZ is available in French, Russian, German, and Japanese.

Pro Zooming with Ctrl-Mouse
The user can easily zoom by simply pressing Ctrl-Mouse.

Pro Windows 7 Jump List makes the user's life easier
Jump List is a useful feature that allows the user to view recent documents in a program that is pinned to the taskbar.

Pro Snippets
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 You can't scroll up and down for command history as those keys are bound to the scrollbox
Con No way to open pre-created tabs on startup
If you want to setup a certain number of tabs to automatically run pre-defined scripts in ConsoleZ or Console 2, you can't. You have to open everything manually every time you start the application.
