After some time, planning to install Linux again for personal use and some dev work at home. My current pc is getting too slow sometimes and it irritates me a lot.

My current pc 2gb RAM, Dual core Intel, 32 bit.

Main criteria, os should be fast, I can compromise on GUI, should be stable, should support my old configuration. I like to work on Java/Scala, python, js and sql. Eclipse will be there since I use it at work.

Short listed Ubuntu 16.04.2 LTS,
mint (huge confusion on gui),
Opensuse, elementary OS and arch. I had Ubuntu, mint for some time as secondary OS. Arch will be totally new world for me. I have tried few OS in USB boot but couldn't fix one.

Right now I am confused about which one to choose, since everything looks fine but I want the best choice based on my criteria.
