Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Amazing file manager integration
Konqueror can also work as a file manager and it does a great job at that. You can view both local or remote files (through FTP, SSH, SFTP, and Samba protocol).
Pro Low footprint in KDE
Konqueror usually has a low footprint when used in KDE because most of the resources needed are already loaded. This makes the startup time and general loading times between commands very fast compared to other browsers in KDE.
Pro Developed by KDE
Pro Lightweight
Pro Free and Open Source
GPLv3 license.
Cons
Con Lacks incognito/private mode
Konqueror lacks the option to browse the web in private mode, which is used when you don't want to leave any search history or avoid saving any cookies or cached data.
Con No large extension support
Konqueror is unable to tap into the large collection of Chrome extensions like many other browsers do. So the options to extend Konqueror's functionality are pretty limited.
Con Weak multimedia support
It has some issues with multimedia content eg. Non-playing videos on webpages.
Con Now under the KDE umbrella
Qupzilla is now discontinued and renamed to Falkon. It will also now be a part of KDE and will probably need more dependencies like kde-frameworks in the future.
Con Linux-only
Con Bookmark management not the strongest part
It often requires quite a lot of clicks to add and remove bookmarks.
