I recently swithced over to Mint 15 from Ubuntu. I think it's been about 3 or 4 months. The other day I was messing around with VBox and realized that I haven't gone to the forum since I first made the switch. Mint runs flawlessly!!! Over the years I found I was having more and more issues with Ubuntu, especially after Unity!!! Outside of getting use to Mate and finding everthing the transition has been painless. I am testing Mint Debian 201303 on Vbox right now and it works nicely as well, however I find Vbox has it's on little quirks.
Just wanted to say how pleased I am with Mint. Looking forward to new developements.
