What os are you using?

Windows 10 Pro, is decent and had no issues with it.

Windows 10 at home, debian 8 at work

Windows 10 Professional and Ubuntu 16.04 LTS dual booted. Works flawlessly for cross-platform development, though the Windows Subsystem for Linux makes some things pointless.

I use multiple on a daily basis, Windows 10, macOS 10.13, CentOS 7
