Pro Can add desktop effects
SliTaz has a feature called "Desktop Effects" which can add shadow or fade effects to windows.
Pro Very customizable
SliTaz is very customizable. You can programatically edit and change anything you want on how the OS looks or behaves.
Pro One of the smallest distributions with desktop GUI
The core liveCD is only 35 megabytes. The boot-from-internet option fits on a floppy.
Pro A separate NVIDIA version
Most linux distros seem to hate Nvidia's graphics cards e.g. Fedora and OpenSUSE. System76 have decided to be kind. They have decided to form a good relationship with Nvidia fans and Nvidia itself. By creating a separate installation media that is dedicated for providing support to Nvidia's graphics cards. Even going as far as putting Nvidia's driver updates on Pop!_Shop for users to easily access and install.
Pro Made by a hardware seller
System76 is a hardware company. It configures machines to ship with Linux pre-installed. This means its entire business model centers around delivering a quality desktop Linux experience.
As a result, the company pours more attention onto the desktop. It can fix visual issues and may be able to provide a smoother overall experience than you would have installing a different version of Linux on your machine yourself. Providing Pop!_OS also empowers System76 to make certain fixes for users directly rather than having to coordinate with Canonical or the broader Ubuntu community.
Pro Pop! makes GNOME look really good
If you're a fan of flat desktop interfaces reminiscent of Material design on Android, you'll like the theme that comes as a default in Pop! OS. The desktop and title bars all use a bright turquoise theme that makes the interface feel happy and borderline retro-chic. I found it to be like something you'd find printed on a ringer t-shirt.
Pro User-friendly installer
The visually appealing and easy to use installer makes dual booting as easy as it can be.
Pro Nice gnome theme dy default
Has nice gnome theme looks really good.
Pro Optimized for modern hardware
Whereas normally, to use a brand new computer with a Linux OS, you would typically try to use unstable and sometimes buggy drivers - or struggle without hardware support until a stable release comes along.
Pro Ready to play games, out of the box
If you still miss how easy it was to just click-install and play games in Windows, Pop! will give you that similar expectation.
Con Install instructions are in French
When first booting SliTaz from a USB or from a Live CD, the installation instructions are in French.
Con Not much variety as to available applications
SliTaz does not have as many applications in its repositories as the bigger distros such as Ubuntu.
Con 64-bit only
Some older PCs still have 32 Bit processors. This limitation will be a major con for those who use an older PC since they will not be able to install, run it in a VM or live media
