I use nord. Honestly, the community is really centered around it's implementations. Nord makes it SO easy to use their theme almost everywhere. Use Vim? They got you. Emacs? Got you? $EDITOR? Got you. Gnome/XFCE/iterm2/etc - yep got you there too.
Honestly, not only is the color scheme excellent (speaking as someone who stares at a computer 18 hours a day) it's so easy to use compared to others it's hard to pass up. Even zenburn and solarized are frustrating to use because of subtle differences between implementations of the palette.
Both Vim [1] and Emacs[2] are on the ports page [0]. In Emacs it's as easy to install as `package-install nord-theme` and then `load-theme nord`. I will note that I tried it out in Emacs running in Windows Terminal and it looks terrible, completely different from the demo and almost unusable - I quickly went back to one of the default themes, tango-dark. This is probably only going to work in the GUI version.
