I would recommend to sticking with the default two for now, until you come across a reason to enable additional repos. I had recently did a fresh install of Kali, (been a while) added the additional Kali Repos, went through the entire procedure up updating and upgrading everything.
Found out on reboot, GDM Broke. Once I figured out why, started it back up, logged into a nice Debian interface o.0
Re-did the install and kept the original repos for now, while installing anything not there that I need as they pop up.
