It looks pretty good albeit I've only tried the live media. I aim to install it on a new HDD I have. I'm not sure whether I'll like Cinnamon and MATE but I did like Gnome 2 and I liked KDE before it had major surgery. Now, my choices are XFCE (not bad), Cinnamon or MATE. I can't stand Gnome3 and KDE is a 2nd choice to the rest just mentioned. If I want something extra from XFCE and I don't like the DEs from Mint, I'll grudgingly try KDE again.
One thing I think Mint does right is installing so many packages by default. One might say, I don't need all of those packages installed. But, it's great for being very versatile and if you don't need certain ones, you can just uninstall them. It's a very good configuration idea especially for newbies and just for testing it on your hardware.
Of course, there might be issues as well but overall, it's a good idea. As long as certain ones don't conflict (and it's just unneeded extra packages) then it doesn't hurt and it's good. I also like that Mint chooses to use Debian Testing so many packages are up to date. I want to get a wifi card for my desktop one day and I'm pretty confident it'd be fine with Mint. With many of them being realtek, I might have to settle for that and I noticed Mint has the latest firmware already installed.
