Pros
Pro Very customizable
From little things like folder colors to larger options like desklets. Unlike gnome and unity, there is an option for almost any desktop preference.
Pro Simple and complete therefore good for ex-Windows users
Cinnamon is one of the simplest of the Linux desktops to use. Everything appears to be at hand, and this is one of the easiest of the Linux desktop environments to get familiar with. It is, as has been pointed out, very customisable. The Mint install with Cinnamon seems to provide just about everything a user would want on their desktop system and it's easy to get at (mostly).
But, like anything Linux, if you want to do STUFF likely you will be at the command prompt (or terminal if you prefer).
Pro Cinnamon provides control of icon placement on multiple monitors
Cinnamon provides control of the placement of desktop icons on multiple monitor setups. This feature has been buggy, but in my testing of Linux Mint 19, this feature appeared to be stable. Thus, Cinnamon joins KDE and Windows in enabling this capability. For example, in a setup with 2 or 3 monitors, you can put the desktop icons on the right-hand monitor. With other DEs, the icons always move to the left-hand monitor.
Pro Lots of configuration options
Both Gnome and Cinnamon got the same looking configuration panel. There are 40 sub-panels in Linux Mint Cinnamon's, whenever there a far less with Ubuntu Gnome 3's.
Windows, notification, smart corners, windows overlay, connexion windows... you can have those in Gnome, but these require compiz and other stuff.
Pro You can easily get it to look like Windows
You can get it to closely look and behave like Windows with considerable ease. This is a good thing for those switching from Windows, because it gives them a familiar environment, cutting down on the learning curve a bit. Among the popular DE's this is the one that gets you closest with great ease.
Cons
Con Crashes
Despite Cinnamon being on its stable second version it still crashes a lot, ranging from plugins all the way to drivers.
Con Uses GTK
Nowadays, GTK is designed with GNOME, and only GNOME, in mind. Non-GNOME applications which attempt to utilize it suffer as a result.

Flagged Pros + Cons
Pro Most similar desktop to the windows experience
I went from Windows 10 to Linux Mint Cinnamon and so glad I have.
Con No access to bleeding edge packages
Linux Mint 17 is based on Ubuntu 14.04 LTS (Trusty), so the packages available are somewhat frozen in (a stable) place due to the LTS status.
If you want more recent versions of packages like available on Vivid and Wily you're out of luck.
