I think that if you want cinnamon then you should use Mint, of course! You can choose between Mint and LMDE, the main Mint is based on Ubuntu and LMDE is based on Debian...
I currently dual-boot Kubuntu and Mint Cinnamon, and this August I just used Mint with Cinnamon, I just uninstalled it because I wanted to try something, but you can work and do whatever with it -just like KDE, not like Unity!
And, if you want to try Cinnamon on a rolling release like Arch, I recommend you installing Arch and then installing Cinnamon, rather than Cinnarch. It's pure and KISS! If you don't feel comfortable installing it, you should try it first on a virtual machine. You'll see it's not difficult as they tell!
