Ranked in these QuestionsQuestion Ranking
Pro Customizable through config files
Just like DWM, bug.n is configured through a plain text file. This is a great resource for setting up your configuration. Original link is down, try this one for the Archive.org copy.
Pro Based on hotkeys
A lot of the other alternatives are GUI based, which are very inefficient compared to the hotkey approach of bug.n.
Pro Open Source
bug.n is free and open sourced.
Pro Saves a lot of windows space
Bug.n can increase the available screen estate by freeing up the space occupied by
the Microsoft Windows Taskbar & the title bar for every single window by hiding and replacing all with a single slim status bar.
The status bar shows the current config of your window setup & can also show system information like time, date and memory usage.
Pro Supports multiple monitors
Pro Very customizable
You can radically change the way bug.n works to suit yourself, although it takes a little bit of work some times.
Pro Disabled very easily (windows+ctrl+q)
This is especially helpful while learning to use bug.n.
Pro Handy resource monitor
Has an own conky style resources monitor in its statusbar showing cpu/ram/disk reads/writes, network uploads/downloads and time
Pro A lot of settings for every window or sub-window that opens
Pro Each window keeps its own position at startup/open
Pro Allows different wallpapers/screensavers for each monitor
While Windows limits your customization to 1 wallpaper and 1 screensaver, which has limitations for certain applications. For example, if your monitors have different resolutions or aspect ratios, wallpapers don't always play nice. Display Fusion lets you have a different wallpaper for each monitor which alleviates issues like this.
In industrial applications, this means that you could have a customer-facing monitor which has a different (more professional) wallpaper and screensaver.
Pro $25 for a lifetime upgrades
Pro Shortcuts for window management
Using keyboard shortcuts, you can lock your mouse to the confines of an area (a window, or even a specific monitor - useful for gaming), as well as resizing or moving the window. These are great additions to the window shortcuts built into Windows (alt+tab, Alt+F4, Win + D, etc).
Pro Windows snap to each other
Especially on large monitors, you may want to have multiple windows open on the same screen. Windows only snaps 2 windows to a screen, but Display Fusion snaps windows to the edge of other windows.
Con Requires AHK
Con Some applications need manual configuration to have them work well.
Con Confusing at first
It is a great program but without a good tutorial. There are a lot of technical documents, which is interesting if there is first a basic tutorial to help the user start. To really understand this software there must be a knowledge of autohotkey. For those familiar with autoit and not autohotkey, there may be a learning curve.
Con Office 2013 windows don't play well
Does not remove decorations from, e.g., outlook 2013 windows.
Con Doesn't play well with Firefox
Mozilla Firefox has captions and titlebars (using Win-Shift-D (show/hide active titlebar) doesn't work in Mozilla windows) that don't play well, meaning they stay no matter how long one tries to remove them.
Con Not nearly as useful for single monitor setups
Most of the features are useful for multi-monitor setups. If you are just using one monitor, you won't be using the majority of the features available in Display Fusion.
Con Window splitting configuration requires manual input
The GUI for window splitting can be a bit tedious to work with - while it offers great customizability, it does require either calculating how many pixels you'd like, or trying it hit-and-miss if you'd like to i.e. fit an IM program with the contact list to a side of the screen. In other words - no real-time preview, and the splits' edges don't travel together when adjusting edges around.
Con Expensive for what it offers
Starting at $25, this program won't offer much utility to most users - however it can be useful for niche users. $5 or even $10 would be an easier pill to swallow.
