Pros
Pro Runs Pre-configured virtual machines
Allows you to run your virtual machines pre-configured by you or others.
Virtual Box versions for:
-- Windows 7/8/10
-- All Linux installations
-- MAC OS x
-- Solaris 10/11
Virtual OSs include:
-- Oracle Linux 5/6/7.x (RHEL clones)
-- Solaris10/11
-- Occassionally a Windows Beta
Oracle itself provides many free VMs, pre-configured with various software stacks and hands-on lab materials for learning, geared toward. These have helped me earn three of my Oracle certifications:
-- Oracle Database development
-- Oracle DBA
-- MySQL development
-- Java Standard/Enterprise development
-- Big data
-- Webcenter portal & others
Pre-installed software in or more of the various stacks includes:
-- Oracle Database 11/12
-- JDK/Eclipse
-- Enterprise Mgr
-- MySQL
-- WebLogic
-- Cloudera, etc.

Pro Supports modern shells
Whether you prefer zsh, bash, or fish, Linux will support it.

Pro Isolated from Windows
VirtualBox provides almost total isolation from Windows running underneath it, removing a lot of security issues.

Pro Free / Libre Software
While the OS underneath it is proprietary and does spy on you or actively violate your freedom, so to speak, you can still have a little piece of mind knowing that VirtualBox (your Linux distro and shell of choice) as well as Terminator are all FOSS.
Pro Official Microsoft product
Pro Is an *actual* terminal emulator--what a Linux user would expect--like xterm
Not a command prompt/processor (i.e. shell) but a host for such applications.
Pro Multiple shell support
Pro Open Source under the MIT License
Pro Easy and well documented JSON settings
Pro Microsoft is nailing on its features
Cons
Con Install a whole operating system for one program
You would need to install the entire Linux distribution just for one single program.

Con Slightly slower than just running Linux
The Windows + VirtualBox layer introduces some overhead that wouldn't be present if Linux were installed directly on the machine.
Con Requires latest version of Windows 10
Con Cannot have a mix of elevated and non elevated tabs
Con Unstable and buggy
Sometimes freezes and/or crashes.
Con Configured via (mostly) documented json
Con Slow
Con Doesn't have feature "Open Context Menu"
Poorly, this perfect terminal doesn't has this feature for Windows version.
