Pro True color and Smooth font

Pro Customize and save profiles

Most terminals in Linux don't support font ligature, while many modern fonts such as PragmataPro or Fira Code already have decent coverage of font ligature. Support for font ligature makes user experience and font management much easier (i.e. you don't need to keep two copies of the same font just to use in the console)
Pro Allows CTRL-SHIFT-c/v within WSL Ubuntu as well, Good menu to customize
Con Not free
The subscription costs $89 per year.
Con No stable portable version
Any portable version present is wrapper. It moves files from portable folder to appdata and backward, which often cause dataloss
Con KDE Library dependencies
While not an issue if using KDE, when trying to use this terminal in other desktop environments or window managers, there will be a large amount of dependencies tied to the app, making for a large install size. For those trying to keep their desktop lean, this may be an issue.
Con Uses a lot of memory
Although it's very fast, konsole has to use a lot of resources in return. It may use up to 30 MB per instance, depending on the number of tabs and the task at hand.
Con Can mess terminal keybinds
Most the of the time, the terminal keybinds are just ignored to obey the kde keybinds. Can be configured though.
Con Lack of DECSCUSR support
Konsole don't allow changing the cursor shape with extended DECSCUSR sequences, using instead the temporary-profile hack. This causes pain when working in (neo)vim inside Konsole.
Con No support for double-width characters
Konsole no supports double width characters. For powerline users, you need to add a space after powerline glyph.
