Pros

Pro Polished look and feel
Fresh installation looks great.
Pro Reliable and working great out-of-the-box
It works on many machines. Really good.
Pro Good but not so good
There's been a lot of effort put in this project through the years, there is no question about it. It's 100% free and it's very user-friendly, but it being based on Ubuntu 16.04 isn't the best thing, as you are working with software that still is actual but the versions are not the newest.
Pro Stable
Tumbleweed is stable enough to use every day. Updates are OpenQA tested to ensure stability before being released for Tumbleweed. Bleeding edge untested software can be tried using OpenSUSE factory.
Pro Easy installation and cutting edge apps
Pro A large amount of software
Pro Tumbleweed + OpenSUSE Build Service
Pro Good selection of preinstalled applications
Pro User friendly + Good support
Active and friendly user community, updates come fast
Cons
Con Avoid proprietary-only GPU drivers
GPUs without libre drivers are a problem (not fault of Trisquel, of course). Also Wi-Fi cards in the same vein.
Con Little / no third-party support
Like it or not, most third parties don't want to deal with less-popular distros. So most of them only support Ubuntu LTS and those versions of RHEL/CentOS that are still supported.
Con Complex multimedia codecs and plugins installation
Con "Online Update" update in YaST control center only works in openSUSE Leap
Con Packman repository has to be added to have good software support
Con Slow and painful unfortunately, especially compared to other modern distros
