I'm a fan of LMDE Mate but I've just tried Point Linux in a netbook and I have to say it is awesome. Is slightly lighter than LMDE, equally easy to use, very stable and nice looking. Based on Debian stable instead of testing, so is not rolling but less prone to breakages when updates are coming. The Point Linux developers have done a very good job.
Respect to the main version of Mint, it can be said that Point, like LMDE, is faster, more responsive on old hardware, but requires a slightly more advanced knowledge / experience. For a new linux user is better to stay with the main edition, IMHO.
Linux: Mint13 (Xfce), LMDE (Mate), Peppermint (LXDE), Manjaro (Xfce), Point Linux (Mate)
