Pros
Pro Windows Live Tile-like vibrant interface
Like Windows Phone 8, the design of Launcher 8 consists of brightly colored tiles on either a black or white background. The result is a simple and appealing design. Although simply changing the tile color is not as personal as wallpaper in conventional launchers. Fortunately though any color is possible on Launcher 8 not just the preselected colors on Windows Phone 8.
Pro Separate widget pages
Windows Phone 8 was never designed to work with Android widgets but that doesn't mean you can't use them with Launcher 8. The developers of Launcher 8 have finally found the right solution to using widgets on the tile interface with new separate pages. In the previous version of the launcher, Launcher 7, the widgets would be squeezed into tiles and the result was rarely good. The new separate widget pages accessible with a swipe to the right are a big improvement.
Pro Transition effects
Launcher 8 uses the same transition effects when opening apps and returning to the home screen as the Windows Phone 8. Not only is this appealing but apps seem to load quicker. The transition to open an app takes a few hundred milliseconds which gives apps extra time to load. The result is an interface that seems quicker than it actually is.
Pro Notification bar can be hidden
This feature may seem counterproductive at first but it provides a minimalistic appearance that stays true to the original Windows Phone 8. The notification bar will still appear everywhere else on your Android but Launcher 8 will be just tiles.
Pro Unread counts
Launcher 8 supports basic unread counts like phone calls and text messages in the free version.
Pro Google Now support
KK Launcher supports Google Now by swiping left in the launcher.

Pro Customisable
KK Launcher supports thousands of icon packs as well as popular themes from many different popular launchers. This allows the user to customize the look of the launcher to their preference.
Cons
Con Difficult to set up
As expected this launcher is much harder to set up than the real Windows Phone 8 launcher. Apps must be assigned to their their corresponding tiles, live tiles are difficult to set up, and setting tiles up to display contextual information is difficult. Fortunately though the developer has been consistently improving these issues.
Con Adware upon install
KK Launcher has multiple adware apps that are built into the launcher upon install, taking up precious memory as well as maybe doing other more nefarious things.
