Pros

Pro Extremely reliable
The packaging team is dependable resulting in system updates that come in a timely fashion and systems which rarely, if ever, break due to packaging. The versions of software that are selected and the configuration of them is typically extremely high quality.
Pro Easy installation and administration
openSUSE makes use of a GUI tool called YaST to install and setup an openSUSE system.
YaST is very easy to use and makes the process of installing and maintaining an openSUSE installation a breeze.
Pro Easily get packages from other sources
SUSE Build Service offers packages from the same sources as Fedora, Debian, Ubuntu, SUSE Linux Enterprise and other distributions. This is the most underused package tool in Linux today.
Pro Probably the best KDE desktop experience
Both Gnome and KDE desktop options are well polished to fit with the opensuse theme and environement, so either desktop is a great choice.
Pro Very stable
Stable, reliable, rock solid.
Pro Amazing choice for both newbies and power users
OpenSUSE is very easy in terms of installing packages, administration and customization, yet very powerful in the same. Every user should find his own piece of cake in this OS.
Pro Supports RPM packages
Popular format shared with distros like Fedora, RHEL, Scientific Linux, Mageia etc.
Pro Built-in drivers
Does the job needed and has the hardware drivers for the application built-in by the H/W supplier.
Pro Dedicated professional community
Directions on other desktop Linux's often force you to use GUI packages or have steps that introduce security issues.
OpenSUSE has a professional community and directions are usually geared toward GUI and CLI with similar steps.
Pro Feature rich
It comes standard with a large number of pre-added applications that sort out your day-to-day use.
Pro "Tumbleweed" Rolling Release
Regular and easy upgrades to stable and well tested software.
Pro YaST
Best administration and setup tool.
Pro One-Click install
Much better system then other distros for installing any package. It is as simple as clicking on one button and typing in your password. Adds a repo to your system keeping everything updated at the same time.
Pro Fast
Applications feel fast.
Pro Convenient package management with Zypper
Fast, reliable, powerful and almost impossible to leave a broken system.
The Yast interface will also give you access to a Zypper GUI if you are uncomfortable with the command line.
Pro Outstanding community support
OpenSUSE has a VERY active user community. Questions on forums are generally answered in minutes.
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 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.
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 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 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.
Cons
Con Some clear differences from other Linux distros
This might be a systemd issue or OpenSUSE specific, but changing certain text files does not update things. They must be edited in YaST, or in /etc/sysconfig/
Con Old kernel by the Leap version
Kernel in Leap 42.3 is in version 4.4, that's pretty old.
Con Poor support for nVidia drivers in Tumbleweed
No native driver support and nouveau may be broken, especially for KDE, and not suitable for some GPUs.
Con Bloated and slow
Con Short lived distro
Every release lasts 18 months only before needing a major upgrade.
Con Updates
Not a huge problem, but Tumbleweed is better updated via the command line.
Con Massive ISO download
The base ISOs are over 4 gigs, so be prepared for a very long DL if you have slow internet. There's a network installer version, but that just delays the long DL.
Con Bad support to NTFS fotmat.
Con Limited community support
The community is fairly small, and there is no indication on the forums regarding when a issues will be solved.
Con Packman repository has to be added to have good software support
Con Startup takes a long time
Con Updates
Not a huge problem, but Tubleweed is better updated via the command line.
Con Complex permissions policy
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
