Pros
Pro Simple and minimal
Plank is a good choice for those looking for something simple that just does its job well. There is no UI for options built in to the dock as to change anything those options will have to be accessed through a text file.
Pro Solid and lightweight
Pro Third party themer available
An additional third party app has been developed that allows theming the dock without the use of any extra resources. This is great for those that are not using elementary OS and the elementary tweaks extra.
Pro Easy to tweak and make your own themes
Drag and drop, change icons, use effects, etc. It's fun to play with. It's not a basic dock program and the GUI is good.
Pro Cairo-Dock session
Users can choose to launch a stand alone Cairo-Dock session where the dock also serves as a taskbar where all apps are launchable such as in any other DE session. There is a composited version and one without.
Pro Popular and usually found and installed from a distros repo
Due to the popularity and how long Cairo-Dock has been around it is more often than not found in a distros repos, which is very convenient to get the app installed.
Pro Easily themed
Cairo-Dock has built in settings to install and use themes for the dock and icons. Definitely more robust in this are than most other docks available for Linux.
Cons
Con No right click menu for some apps outside of elementary OS
Other file explorers and terminals (those not found in the default elementary OS) do not have any right click menus for the dock meaning it is impossible to launch multiple windows for certain file explorers or terminals.
Con Poor workplace awareness (cycling windows)
When configured to only show apps on current workspace, cycling an app open on multiple workspaces will switch workspace focus, update the dock and often leave you to cycle another app.
Con No updates since 2016
Certainly no PPAs for modern releases of Ubuntu.
Con Poor/No system theme or icon integration
Docks use their own theme, own theme colors, icons, layout's and theme engines.
Con Hard/Underwhelming to configure
Cairo dock proposes a feature rich tool, tweakable to any degree. The configuration menus are at times inappropriate, shallow and uninteresting, complex to navigate, and prefab-centric. Rarely offering a satisfying preset, and always unsatisfying to tweak.
Con Can be heavy on resources for weaker systems
Cairo-Dock is more on the heavy side when compared to other docks, which is something to keep in mind for those that are on low resource systems.
