It put Arch (what I use) first, immediately followed by nixOS for me.
I'm really tempted to install and play with it, the premise sounds awesome, however time is not infinite
Same for me, although I currently use Antergos which is (kind of?) based on Arch, third on the list for me. Was already wondering if I should try plain Arch Linux or NixOS sometime, will probably give both of them a try soon.
