ParrotOS is certainly an alternative to Kali & BackBox. I've been using it for about a month and had very few problems. It comes with Mate instead of Xfce or Gnome and has a blackhat vibe. The only issue I've had is installing it on a MBP [retina]. That has been an issue from the beginning and I still haven't been successful. It's the new kid on the block, but nonetheless a great starter distro.
