Ranked in these QuestionsQuestion Ranking
Pros
Pro Allows you to stay in the terminal
Since it runs in a terminal, it may live within ssh sessions, tmux/screen sessions, etc.
Pro Nice Themes for a terminal app
Vifm has a lot of good themes that you can easily grab from the main site and use with the :colorscheme command.
Pro Configurable
You can easily configure almost all aspects of vifm by just editing the dotfile which is pretty easy is you are comfortable with configuring apps.
Pro Great integration with vim
The vifm.vim plugin allows you to use vifm as a powerful filepicker for vim.
Pro Default key mappings will be comfortable to vim users
Vifm uses vim-esque key mappings. Makes for extremely efficient and---perhaps more importantly---intuitive interactions. The key mappings can be changed.
Pro Dual pane
The dual pane nature of vifm makes copy paste and moving files from one folder to another super easy.
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 All common operations can be done with keyboard efficiently
In addition, shortcuts can be easily renamed.
Unlike Dolphin and many others.
Pro SFTP support
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 Can view and edit many files
Even editing a file inside a .zip file.
Has hexadecimal viewer embedded for binary files.
Pro Filename association and instant console availability
Pro Multi-rename tool
Pro Searching capabilities and copying/deleting/moving in background
Pro Custom commands can be added to the menu easily
And they can use the current folder, the selected files....
Cons
Con Useless for non-vi users
Even to quit one has to use ":q".
Con Very high learning curve for newbies
Con Can only be used in terminal
Vifm lacks a standalone GUI option.
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.
