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 Software management and updating made simple through Synaptic
Pro The team is headed by Texstar
One of the best in the business.

Pro Rolling release model
No reinstalling the OS after every major upgrade. Keep your OS updated, and you have the latest version.
Pro Helpful and knowledgeable forums
Many issues can be resolved by just searching the forums. They are really a storehouse of knowledge. If not, expert help is still available.

Pro "Batteries included" philosophy
Main release includes most apps needed by users everyday. Windows users will see a familiar look and feel to the UI. H/W issues practically nonexistent, as most drivers come with the ISO.
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 No 32-bit version

Con Gaming can be hit or miss
To run some titles, particularly from Steam, some "massaging" is necessary.
