Pros

Pro Covers
A more powerful alternative to folders, Covers allows the user to disguise what would normally be a folder as an app one of the apps in the folder. One tap opens the app normally, but swiping up on the icon reveals the folder that the icon is covering. The use of covers is also optional for those that would rather use a regular folder.

Pro Quicktheme
The action bar and search bar change colors according to the wallpaper, making for a great way to have a consistent color theme.

Pro Supports icon packs
Pro Active, Innovative Developer
The dev constantly releases betas and trials new features. Bugs are found and sorted out quickly. App innovations are often ahead of the curve -- e.g., quickdrawer, instant theming, pixel integration before Nova, gesture integration. When upgraded from AL2 to AL3, the dev also explained the rationale behind the move to a whole new app and payment, and discounted supporters.

Pro Gestures for shortcuts
Use swipes, pinches, and multi-finger gestures on the homescreen as shortcuts to your favorite features. A favorite is a down swipe anywhere on the homescreen, to bring down the notification tray so users don't have to reach up to the top of their screen. Additionally customise double- and triple-taps on the homescreen to launch a variety of options.

Pro Pixel Launcher look & feel
Use the Pixel theme to add a dock background, and add a Google pill button instead of the search bar. this way users can mimic the look of the Pixels launcher.
Pro 1 Google Now page
With a companion app Action Launcher, you gain access to the Google Now page.
Pro Sliding quickdrawer allows for quick access to apps
The quick drawer allows for quick access to apps, from anywhere on the device. This way users do not have to go to the home screen in order to open the app drawer.

Pro Shutters
Shutters is a feature that allows the user to swipe up on an icon to load the app's widget in a small window, and then hide when done. Saves tons of screenspace without losing the functionality of your favorite widgets.

Pro Lightweight
Pro Google Now support
Action Launcher 3 supports Google Now "Ok Google" voice search allowing users to voice search from the home screen.

Pro 3D Touch-like app shortcuts
Pro Does not slow down under load
Pro 'Vertical grid' app tray option
Action Launcher has the option to enable a vertical grid app tray that acts like most menus that slide out from the left of the phone's screen. Apps are organized alphabetically, and touching a letter will take you to apps that start with that letter.
Pro Feels great with curved displays
Action Launcher 3 feels like it was made for curved displays, like the Galaxy S6/7 Edge, BlackBerry Priv, and Nexus 4. Swiping in from the edge for the vertical app drawer or quickpage feels even more natural on these phones.
Pro Easy to use, card-based interface
The home screen is organized into cards that can be scrolled vertically. Cards can contain widgets or collections of apps. Swiping from the left gives access to all apps and swiping from the right gives access to all widgets. These can then be added to the homescreen. It's possible to customize the order, color, transparency, size and what how much information or apps a card displays.
Pro Clean, material design inspired aesthetic
The look of the launcher is inspired by Android 5.0 Lollipop and material design. It follows material design color scheme, has a card-based layout and a Google Now-like, header with a stylized image of a city at the top of the homescreen that changes throughout the day.
Cons
Con Misleading description of the free version
Most of the features are in the upgrade version.
Con No trial for the pro version
There's no way to try the pro version before buying it.
Con Confusing upgrade procedure
Action Launcher can be upgraded to the Pro version using an in-app purchase. The confusion comes from the fact that there's a Pro version available on the Play store, but the correct version to upgrade is through the in-app purchase.
Con Cannot change icons without upgrading
Cannot change the icons individually without upgrading. Some icon packs do not change all the icons when initially applied.
Con Interface is not optimized for widgets that can be scrolled
Since the interface is based on vertical scrolling cards, widgets that can be scrolled (like a calendar widget) can get in the way of easily scrolling through the list of cards. It is possible to turn off widget scrolling in the settings to avoid these issues, but limits functionality of widgets.
