Pros
Pro Blazing fast
Fast Git GUI. Everything is already there and loaded when you open up the window.
Pro Allows doing complex things without memorizing git
Git usage beyond basic checkout/commit is arcane; GitUp lets you do things in git in seconds that would take you a half hour of research with the command line.
Pro Full undo
You can backup, or edit commits, if you make a mistake.
Pro Open Source, GPL-licensed
Pro Uninterrupted workflow for common tasks
Simple tasks, such as commits, can quickly be made without leaving the editor.

Since it's integrated with Emacs, diffs are very easy to fix. You can jump right to any file you want to fix as soon as it comes up in the logs or in the status view.
Pro Easy to remember mnemonics
You can easily learn the mnemonics for the most common tasks and use them to your advantage to speed up your workflow.
Pro Better visualization and interactive workflow
Pro Stage hunks or even just parts of a hunk using a single key press
In Magit staging a hunk or even just part of a hunk is very easy.
Magit also implements several other "apply variants" in addition to staging and unstaging. For example: you can also discard or reverse a change, or apply it to the working tree.

Cons
Con OS X Only
Only available for OSX, so if you are used to working with different OSes and you want the same tools in each of them, it's impossible to have that with GitUp.
Con Font size is not adjustable
Tiny font not good for those with poor vision.
Con Useful only for people who use Emacs
Magit is only useful if your text editor of choice is Emacs. It wouldn't really make any sense to open up emacs just to run Magit if you use another editor.
