Ranked in these QuestionsQuestion Ranking
Pro Great two-pane interface
Pro Folder synchronization
Pro Handles most archives. There is little difference in behaviour between an archive file and a regular folder.
Pro Virtual file systems
Search results as example saved into virtual folder and can be accessed later. All file operations may be performed on items in search results as if they were files in single folder.
Pro Many operations like copying and moving files can be queued
Long running operations can be queued.
There is no point in doing them in a parallel way, as speed decreases dramatically.
Pro All common operations can be done with keyboard efficiently
In addition, shortcuts can be easily renamed.
Unlike Dolphin and many others.

Pro Custom commands can be added to the menu easily
And they can use the current folder, the selected files....
Pro Filename association and instant console availability
Pro Multi-rename tool
Pro SFTP support
Pro Innumerable button-click file ops are integrated
Rename files, move to other directories and extracting archives are of course a given...BUT THERE'S MORE! Convert media formats, make symlinks, CHMOD, change graphic formats, integrated GPG, filename UPPER/lowercase adjustments and more with just one button click!
Pro Remote access
Worker supports access to remote machines through various ways (ssh, ftp, rsh, http and webdav).
Pro Low system requirements
The system requirements for Worker are pretty low, making it a great option for lower-end machines. The reason why they are pretty low is because Worker is basically made of just X11 libraries.
Pro Configuration GUI
Worker has a built-in configuration GUI.
Con KDE dependencies
If you don't use KDE, you'll be forced to install quite a large amount of KDE libraries.
Con New releases are infrequent
It can be seen in https://quickgit.kde.org/?p=krusader.git that maintenance work is done in a continous fashion, but no new releases are provided.
Even though it is perhaps the more feature-rich file manager.
