Pros
Pro Great GitHub integration
This is the official GitHub desktop client built by the GitHub team.
Pro Simple, streamlined GUI
GitHub Desktop uses an extremely simplistic two-panel view. It's not capable of complex historical visualisations like other GUIs, but it is very easy to use (especially for git novices).
Pro Supports pull requests
In addition to being able to seamlessly and easily integrate with all of GitHub's features, it also supports forking and submitting pull requests on any open source project hosted on GitHub.
Pro Context based help
No need to memorize a ton of keys or crawl man pages, gitui only Shows you the valid keys depending on your current context.
Pro Intuitive key shortcuts
Perfect for developers who hate to leave their keyboard.
Pro Very fast even in massive repos
Most alternatives crash or run out of memory when opening 1M+ commits repos line Linux.
Pro Free and open source
Pro Crossplatform
Supports macOS, Linux, and Windows.
Cons
Con Limited
Can't handle complex tasks. The Help Manual advises to use command-line Git instead.
Con Does not support multiple Remotes for a repo
Only allowed to assign one URL as remote. To manage/sync/fetch other remotes, use command-line Git instead.
Con Overly Simplified UI
UI that is designed not to support the needs of power and enterprise users. Management of more than five repos is next to impossible.
Con Buggy
Poster child for authors' programming ideology (FRP), likely the cause for the odd quirks and bugs it has.

Con Not free/libre
This application is proprietary, and thus cannot be modified or freely distributed.
Con No Linux support
There's no Linux version of this client.
Con Non-GitHub repositories are not fully supported
Since this is mainly a GitHub client, other repositories are not fully supported and with as many features and setting up a repo hosted anywhere else but GitHub is troublesome.
Con Terminal is not for everyone
It fills a niche between full-blown GUI apps and the bare git CLI.
Con Lacks some features
It’s still in active development and catches up quickly.
