Pros
Pro Allows quick access to the terminal system-wide
TotalTerminal is a plugin for Terminal.app. It provides persistent Visor Window which slides down when you press a hot-key.
Pro Quake style window show/hide
You maybe know or don't know Quake from Id Software. But this game had the best idea to hide/show a terminal window. Simply using full width but 26 rows. On show the widow slid down from top of screen. On hide it mode up to top edge of the screen until it disappeared. 2nd next best was the semi translucent background. You could still see through the terminal window while it was shown.
The same style is now available in TotalTerminal and iTerm2 (OSX Terminal replacement - no Terminal plugin).
Pro Has keyboard shortcuts
Although it's not in the same level as something like bug.n, Divvy does support the use of keyboard shortcuts to move windows about. You can even create custom shortcuts.
Pro Requires virtually no configuration & is very easy to use
Divvy uses a drop and drag style UI that's simple to use and doesn't require any setup or configuration to get started.
Pro Reasonably configurable
You can change the grid dimensions and a very other visual settings to suit your needs.
Pro Super-fast access by defining your own hot key (mine Win+S)
Cons
Con No longer under active development
Con Doesn't work on El Capitan with SIP on
Apple introduced a new security feature in OSX El Capitan, called System Integrity Protection, that, among other things, does not allow augmenting Terminal. While it's possible to turn SIP off (instructions on how to turn off SIP and get TotalTerminal working on El Capitan can be found here) it is not recommended.
Con Quite inconvenient to assign windows
You always have to use the mouse instead of having proper keyboard shortcuts.
Con No longer updated
While this may work for current machines, the last beta version (to be found on the site) is from January 2016.
Developer's twitter account has stopped being active as well, on November '16.
Con Windows 10 buggy
Not all keyboard shortcuts work. Support is non existent.
Con Installer requires admin rights, installs itself to AppData of the used account
Something to consider if would be used in a restricted environment.
Con Not free
Costs $14.
