When comparing Ubuntu GNOME vs Pop!_OS, the Slant community recommends Pop!_OS for most people. In the question“What are the best Linux distributions for Mac?” Pop!_OS is ranked 9th while Ubuntu GNOME is ranked 20th. The most important reason people chose Pop!_OS is:
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.

Pros
Pro Combines the most popular desktop environment and the most popular Linux distribution
Ubuntu Gnome is an officially recognized Ubuntu derivative. Ubuntu is the most popular Linux Distribution for Desktop and Laptop Personal Computers and is also widely used on Servers. Gnome is the most popular Desktop Environment for Linux Operating Systems.
Gnome's Desktop environment is modern, sleek and designed to get out of your way, so you can just work. It is customizable and once you click around, and see some of the features you can add and change, you will find Ubuntu Gnome provides for a very fast and comfortable work or play environment.
Pro Offers a pure Gnome desktop experience
The Gnome desktop environment included in this distribution is untouched, offering a pure Gnome desktop experience. In addition, all the important Gnome apps are already installed, such as Nautilus file manager, Evince document viewer, Evolution personal information management application, Gedit text editor, Cheese webcam software, Empathy multi-protocol instant messenger, and many others.
Pro Simple and easy to use
Has been designed to be easy to use, modern looking and attractive, and easy to customize and personalize.
Pro Very easy
Pro High modifiability of interface by GNOME - shell extensions
With extensions may looks GNOME environment like Unity, Mac, Windows, Cinnamon or what would you like.
Pro Interface is 'lighter'
Not as graphics intensive as the Ubuntu desktop. Seems to run better and faster with fewer resources.
Pro Hot corner brings up favorite list bar, previews of all windows AND extra desktops
Hot corner brings up favorite list bar, previews of all windows AND extra desktops. Or just hit "windows" key and anything you want is there. Much faster than shortcuts. Gnome 3 speed, with Ubuntu software and support. Bang!
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 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 Nice gnome theme dy default
Has nice gnome theme looks really good.
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 Ubuntu is already using GNOME
As of 16.04
Con Relatively high system requirements
The Gnome desktop environment is a resource hog which requires hardware accelerated graphics rendering in order to run smoothly, making out of the box Ubuntu Gnome unsuitable for low end systems and older hardware. Even mildly aged hardware, you'll get far better performance out of a lighter desktop environment like LXDE or XFCE.
Con Redundant
There is absolutely no reason to install it, since it uses the same package repositories as Ubuntu and you can transform any Ubuntu install into a Ubuntu GNOME install.
Con Some areas of Gnome are unpolished and lack features
Some aspects are still unpolished and lack features - the Gnome design team works well, but seems to not be taking input from the outside world.
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
