When comparing Lubuntu vs Pop!_OS, the Slant community recommends Pop!_OS for most people. In the question“What are the best Debian-based Linux distributions?” Pop!_OS is ranked 27th while Lubuntu is ranked 62nd. 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.
Specs
Ranked in these QuestionsQuestion Ranking
Pros
Pro Part of the Ubuntu family
Being based on Ubuntu (which itself is based on Debian), there's a good amount of information and support to be found when searching for it, both on Lubuntu specifically and Ubuntu that also applies to Lubuntu. It also means that there are certain security and usability standards enforced and you can use Ubuntu .deb packages.
Pro Lightweight
By utilizing minimal software Lubuntu is able to use less resources and power.
Pro Stable
Pro LXDE desktop
Lightweight X11 Desktop Environment performs fast and conserves resources.
Pro Offers a long term support release
Lubuntu offers a long term support release with their 14.04 Trusty Tahr based version.
Pro Uses Openbox as the default window manager
Lubuntu (LXDE) uses the lightweight Openbox window manager to manage its windows. By using Openbox by default LXDE is able to remain lightweight as there is no built in composite manager in Openbox to take up resources.
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 No composite manager
Being a modern desktop many users expect compositing, even on lightweight systems. Without compositing there will be screen tearing, a lot of it. Though there is built in support for users to add their own compositors such as Compton.
Con Long term support not as long as other Ubuntu spins
Lubuntu has not always had LTS support. Luckily they do offer a 3 year LTS now but it is shorter than other Ubuntu spins that receive a full 5 years of support.
Con Clock in panel is broken currently in LXDE
The clock panel applet does not work as expected in the newest versions of LXDE. If the clock is set to not show seconds in the display when waking from suspend the clock will not update until the time actually changes in the applet which means it can take up to a minute for the clock to update when seconds are not shown. The work around to this is to display seconds on the clock which allows it to update after suspend within one second. Sadly the clock does not display seconds correctly as it skips them by one to three at least once a minute, often more.
This is also not the first time there have been problems with the panel clock which clearly illustrates this to be an ongoing problem for the developers.
Con Lacks some window management features
There's no built-in way to snap windows to the sides, re-size them by double clicking the bar, or dragging to the edges.
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 Lubuntu install.
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
