git-gui VS QGit viewer

Is a tool for creating commits and managing branches.

A graphical interface to git repositories

User-Friendly Interface
Git-gui provides a graphical interface for managing Git repositories, which can be more approachable for users who are not comfortable with command-line interfaces.
Visualization of Changes
Allows users to visually see changes in their repository, making it easier to understand the state of the repository and the changes being made.
Built-in Tools
Git-gui integrates common Git tasks such as commits, merges, and reverts directly in the interface, saving time for users by not switching between tools.
Cross-Platform Support
As a part of the official Git suite, git-gui is available on multiple platforms, including Windows, macOS, and Linux.
Lightweight
Git-gui is a lightweight tool that doesn't require significant system resources compared to some other graphical Git clients.

Limited Advanced Features
Compared to other Git GUI clients, git-gui might lack some advanced features or integrations that are available in more comprehensive Git management tools.
Basic User Interface
The interface design is quite basic and might not have a modern look, which could be less appealing to users accustomed to more polished software.
Learning Curve for Complex Tasks
While the interface is good for basic tasks, handling more complex operations might still require a deep understanding of Git or the use of the command line.
Limited Community Support
As a less popular graphical tool for Git, there might be less community support or fewer user-generated resources such as tutorials and forums.
