Linux for reselling PCs, Best distro?

Okay so where I work, they decided to sell some PCs with linux on them, none of them know what its like really, but I am looking at a distro for people that use windows majorly, but only browse the web and do office stuff (Easily covered in Linux) but I am looking at a distro that is windows style, but is linux, There is Zorin OS, Also could use something like Mint or Ubuntu with KDE, or Manjaro KDE.

Which you think would fit the profile better, Zorin 6 LTS is the first up, but I think manjaro would be better, as you dont need to reinstall really.

Thanks!

I used to fix up laptops and throw ubuntu or mint on them anything realy its not likely to stay on there anyway after its changed hands.

i use mint, it's xp like so it goes over well 

Cooperman response did you get to having them on? the people who come to us are not generally computer literate they just want the internet.

I was tempted via mint, but also manjaro for easy updates

Skint student's where buying them and then installing windows on them thay where perfectly usable running mint the mint os holds your hand and is easy to use for someone that has never used linux before.

My step dad is in hes 70's and can use it i installed it on hes very old xp laptop sometime ago and he likes it.

Zorin 

hmm, I think ill have 2 systems side by side one with Mint, one with Zorin, let them decided what they want me to install

Don't rule out ubuntu. Unity is actually pretty decent for beginners, I had it installed for my parents for a long time before I switched over to manjaro and they were pretty comfortable with it.

Linux Lite, and Elementary are also very new user friendly.
