When comparing dwm vs UWM, the Slant community recommends dwm for most people. In the question“What are the best window managers for Linux?” dwm is ranked 5th while UWM is ranked 46th. The most important reason people chose dwm is:
Dwm is part of the [suckless suite of tools](http://suckless.org/), and encourages users to extend and configure it by modifying the code itself. To this end, dwm is kept under 2000 SLOC, and is an exemplar of clean, readable code (C). This, while giving users all the flexibility they could ask for, also makes dwm as lightweight as possible, and means that users have a full understanding of how it works.

Pro Encourages user modification
Dwm is part of the suckless suite of tools, and encourages users to extend and configure it by modifying the code itself. To this end, dwm is kept under 2000 SLOC, and is an exemplar of clean, readable code (C). This, while giving users all the flexibility they could ask for, also makes dwm as lightweight as possible, and means that users have a full understanding of how it works.
Pro Simple and small
Dwm is a low-resource window manager that is entirely simplistic in design.
Pro Application grouping with tags
Dwm's design paradigm is to use tags to group clients (applications) that can then be pulled into a view (workspace); this allows you to view multiple clients at once and to assign or reassign those tags and their related views on the fly.
Contrary to most other window managers, when you view a tag you are not ‘visiting’ a workspace: you are pulling the tagged windows into a single workspace.
Combined with rules in the
config.h, this makes for a flexible and responsive means to manage your workflow.
Pro Default keybindings and functionality are very useful and well thought-out
An example of this is the application of alt-tab to switch between two tags.
Pro Easy to configure
Configuring dwm is straight-forward thanks to its config.h file (though it will have to be rebuilt for the effects to take place).
Pro Useful and informative status bar
The dwm status bar can be set to display all kinds of useful information, such as volume level, wifi signal strength, and battery notification.
Pro XRandR/Xinerama support
Dwm has support for XRandR and Xinerama, allowing for multi-monitor support.
Pro Window hex menu
UWM utilizes a hex menu for interaction with each application menu. This allows each window to forgo the normal open/close buttons found on the border, giving each window a very uniform look. The hex menu is brought to focus by clicking on any application's window border.
Pro Easily accessible online documentation
While some portions of the documentation are incomplete, the important parts (first start, command line options, configuration, etc.) are well written and easy to find.
Pro Can be used on almost any Unix-like OS
UWM can run on just about any Unix-like OS as it is extremely lightweight and only has one required dependency: X11.
Con No runtime config file
There is no config file that can be edited after the window manager is compiled: all changes need to be made prior to compiling.
Con By developers, for developers
Basic knowledge of C language, general programming, and compilation are all required.
Con Limited keyboard shortcuts
There are limited keyboard shortcuts supported in UWM (though more are planned for upcoming releases).
