My favorite is Ubuntu. What about you?

[Skullmeat]

Debian, or Windows 7.

Windows 10 is nice feature-wise but muh privacy. I'd say Arch Linux is really up there. For servers, my tool of choice is Ubuntu 14.04 LTS Server. Can't beat its ease of use and stability.

At the moment I'm with the 'just uninstall the bullshit' package on w7.

[catalinvozian]

At the moment I'm with Linux but I was with Windows 8.1

[Mortem]

Windows 10 or Arch Linux.

Windows 10 ain't bad though
