Whether a distro is user friendly or not, each user decides that for himself. It is very subjective and depends on what the user is expecting from the distro, and how well the distro meets up with those expectations.
That said, Linux Mint is generally labeled user friendly for users new to Linux (and for user not tech savvy). It comes with sensible default applications for working with photos, connecting with others on the Internet, reading and writing documents, playing back music and videos, and so on. Out of the box it supports most multimedia content on the Internet, meaning you can just start using it and won't have to first install all kinds of programs to get that to work. A non-threatening Software Manager and Update Manager make it easy to install new programs and keep them up to date, and Linux Mint by default ensures risky upgrades that could break your installation aren't installed. All the editions of Linux Mint feature a user interface that can be described as an implementation of the "classic desktop", so most users will fit right in.
