Getting started with arch was pretty messy. But once I took the plunge it was a sort of revelation. I was working with couple of arch spinoffs like Antergos, Archex, Manjaro, Archlabs etc. But finally decided to go for the true one and setup one of my own. Choose KDE as my DE and after I got it up and running it was pretty light on my machine.After logging in it kinda takes 500 MiB of RAM and seems smooth. May be I have to do much more customization and all. But above all I am enjoying having almost complete control over my machine.
