Pros
Pro Customizable keyboard shortucts
Moom comes with many preset keyboard shortcuts. The user can go into the graphical settings of the app and change any one of them to a different combination of keys.
Pro You can save tiling window position and size
Users can set window position and size themselves, allowing for a great way to set up a tiling window experience.
Pro Windows can be snapped to the edges of the screen
In addition to using the grid or the overlay, Moom can move and zoom windows by dragging them to screen edges.
Pro Simple customization
While you can set keyboard shortcuts, Moom has a very easy-to-use GUI and GUI-based customization features to help you get going right away.
Pro Adds a zoom button for all apps
Moom adds an overlay zoom button to the corner of all apps which allows any app to go full screen or be placed to certain sections of the screen (such as the top, bottom, or sides). This works even on apps that do not normally allow for full screen views.
Pro Multi-monitor support
Moom has excellent support for multi-monitor setups. You can drag a window to the edge of your screen into another monitor and snap it there.
Pro Best-in-class gaming performance
Compared to other VMs, Parallels has the best gaming performance. Still, a good framerate can only be achieved with games that have very low resource requirements. A much better option for resource intensive games is dual booting Windows (via Boot Camp).
Pro Easy to use
Parallels has an easy to learn and use UI. All important features are wizard based. It requires only a few clicks for the wizard to download and set up the latest Chrome OS, Windows or Linux build.
Pro Can run Windows apps as native OS X apps
Parallels has a "Coherence View" mode that allows running Windows applications as if they were native OS X apps. In this mode Windows is virtualized in background and Windows features like Jump Lists, Taskbar, Start Menu, etc can be embedded directly within OS X.
Pro Best integration ever
Cons
Con UI for settings can be confusing
The settings for the app are pretty jumbled and are hard to get a grip of, especially for first time users. While all the settings one would need are there, they are difficult to find or understand, which requires a good bit of playing around with the settings in order to get a feel for them and what they offer.
Con Not free
Moom is not free: it costs $9.99.
Con Non customisable popover
The pop over is not customisable and has two presets which are odd for instance two presents are two split windows horizontally.
Con Two steps needed, while some tools only need one
Con Very expensive
Parallels upgrades are very expensive. Even if I bough several versions of Parallels I will switch back to free VirtualBox as they even "invented" the Pro version - mainly doubled the price you have to pay each year to have the software updated.
Con Can't import OVA files
OVA files are useful because they include all of its supporting files. Unfortunately, Parallels doesn't support these useful files.
Con Requires buying a new version of the software with each new OS X release
Chances are that the same version of Parallels won't work with different OS X releases, requiring a separate purchase of Parallels for each OS X version.
Con Home edition doesn't work with Vagrant or Docker Machine
Make sure you purchase the Pro edition (the subscription) if you need command-line access to the hypervisor.
Con Can't export OVA files
One you use parallel you get trapped into a proprietary format.
Can't share disk blocks on two unrelated virtual machines (KSM for disk) too.
