Here's some brief background. I've been a hobbyist in the infosec field for 20 years. I remember l0pht etc. I haven't always been practicing, but I read infosec sites, cves, concepts etc. I've decided to get more involved in the past year or so, attending school, and obtaining certs. I've been running Kali, selected because it seemed to be the go to. It's great, I've always had a soft spot for Debian.
Yesterday I grabbed a BackBox vm and really loved the feel of it, but noticed that compared to Kali it seems to be a much smaller tool set. I realize that I'm never going to use all the tools in Kali. I also realize that I can apt-get or add whatever I need to BackBox. I'm tempted to make the switch. What I'm looking for is someone to sell me on it. Convert me to BackBox. Give me user experience notes, solid comparisons, etc.
I searched the web and there aren't really much in the way of technical comparisons. So convert me!
