Ranked in these QuestionsQuestion Ranking
Pro UI design consistency
Excellent uniformity between all the stock application and an overall extremely clean design with simple animations.
Pro Extremely user-friendly
This distribution promises you a very tailored user experience and it does deliver on that promise. The developers provide you with a custom desktop environment and a set of neat programs. And the whole desktop looks simply gorgeous.
Pro Lightweight & fast
Runs well on limited-resources hardware, including netbooks or chromebooks.
Pro If you like MacOSX the UI/UX is similar
Pro Built on Ubuntu
Built on Ubuntu LTS with all its qualities and support.
Pro Active Google+ community
There is a place where Elementary users can ask their questions and usually get answers pretty quickly. Not only by the other users, but the devs are pretty active themselves, often engaging in the discussions on the hows, whys, and plans of the OS.
Pro Simplicity, limited configurability
Sane defaults with less confusion for new users.
Pro Consistent development practices
All Elementary apps are written in Vala and hosted on Launchpad, and there are standard APIs such as contractor for applications to interact with one another. This is different from most distros, in which apps are written in a variety of languages. This design decision makes it easy to get started developing for Elementary and to understand how the various pieces fit together.
Pro A dedicated StackExchange site
Elementary OS has a dedicated StackExchange site where users can easily find answers to common questions.
Pro With new tweak tools customisation is not a problem
Now the OS is amazingly customisable
Uses stable, plain-vanilla packages from upstream.
Pro Ideal to learn more of Linux
Follows the original Linux roots. It still sees Linux as a free clone of UNIX so the distribution tries to be UNIX-like.
Pro Strong adherence to UNIX Principals
Pro Package management
Uses standard tar archives with shell scripting as packages.
Pro Oldest surviving Linux distro
Besides Debian (which was first released in August 1993), it is the oldest still maintained Linux Distribution and was first released in July 1993.
Pro One more distro which is init based
Some users don't like to install systemd based distros because they increase booting and processing speed.
Pro Super fast
Pro No systemd
Con UI doesn't let you change anything
Every installation of elementaryOS looks exactly like the same.
Con Old base and applications
The slow release schedule makes the applications outdated. It drags behind Ubuntu LTS (on which it's based) which itself drags behind Ubuntu which is often still quite far behind Arch for example.
Con Outdated or bad default applications
Con Quite buggy
Con Very slow development cycle
Elementary does not offer any release date for their stable releases going more with an "it's done when it's done" attitude. Making depending on newer apps a difficulty as well as a poor choice for those that need consistent release schedules for their OS.
Con Not very configurable
Con Poor Linux community reputation
The devs of elementary OS feel anyone not paying for their Ubuntu respin are not worthy of using it. Which upset a good bit of people. Obviously the core dev team have issues with their community outreach and PR.
Con The desktop doesn't let you to put icons by default
Con Limited and outdated packages
Packages can be very outdated, and many can't be installed from official repos.
Con Doesn't support 32-bit hardwares anymore
One can install pantheon DE from new ubuntu's repo but Elementry OS is not making new ISO's nor is it supporting them. It makes confuzzled to new users.

Con Emacs doesn't work
Emacs crashes due to a partial gnome library update.
Con Heavy animations

Con No proprietary driver installer
Elementary OS removed the driver installer of Ubuntu.
Con Problems with basic functions
Problems often arise with functions like keyboard layout and touchpad.
Con Boring UI
It can be very boring.
Con Not user-friendly
It is made to be KISS (keep it simple, stupid), so you have to do everything by hand.
Con Large size live ISO
One needs to vain 3GB+ data for downloading one slackware ISO.
Con Niche/small community
Slackware is its own niche and has a small community.
Con Very slow release cycle
Hasn't updated in 3+ years.
