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 Stable
Pro Good Selection of pre-installed software
New users may be unaware of what software is available for Linux, but Zorin includes a good selection for everyday tasks out of the box.

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 Limited desktop styles in Free Version
All free editions only offer Windows XP, 2000, and 7 and Gnome 2. You have to pay $9-10 in order to get Unity (Ubuntu) and Mac OS X themes.
Con Even with v16 Pro, zero tech support replies
Do not pay for Pro. You’re supposed to get tech support with your $39 purchase. After contacting them a few months ago about the inability to install build tools due to their wonky custom versions, to date there has been no answer. You could find a friend and get them to send you the theme and look packages. The rest is all available easily in the Ubuntu catalog.
