Which One Shoud I Use?

Nowadays, there are a lot of Linux distributions and sometimes, it can make people confused. If you ask to someone else, they might give an answer with their preferred distribution, so i usually never pick specific distro and let them choose by themselves. If you are looking for a good Linux distribution, i suggest you read this nice article:
- Choosing a Linux Distro Part 1
- Choosing a Linux Distro Part 2
- Choosing a Distro - Newbie Guide

And if you want better interface, try this website. From this website, i get this results:
- Slackware
- Gentoo
- Arch Linux

Hm... nice... exactly as i used currently (Slackware)

Don't forget to look at DistroWatch for more information about the Linux distribution that you are going to use.
