I, for one, appreciate having those Debian-based distros out there; they do come in handy at times. I also appreciate all the time and effort that goes into them.
It's kinda humorous to me how people here pile on the OP for what they call "trolling," but maybe some of you ought to relax and chill a little bit. This thread could have been a nice, friendly discussion but some folks just want to go on the attack. Too quick to jump in and put somebody else down, in my opinion. What's up with that???
I'm mainly using Debian (and Arch) these days, but I have an Antergos installation and a BunsenLabs installation, and I keep MX and GParted Live (another handy Debian-based distro) on flash drives.
MX, BunsenLabs, and Linux Mint are kinda nice for when you want a quick, easy installation and setup. Debian is fairly easy to install, but there are times when it's really less of a hassle to go with something else. I have one sorta problematic computer that I don't use much, but I don't want to get rid of it yet, so I have BunsenLabs living there.
With many of these Debian-based distros, the live sessions still seem better to me than what Debian offers. MX is excellent for live sessions, as was Mepis. I like to play around with Knoppix in live sessions sometimes (mainly to see what's going on with that distro -- Knoppix was one of the first Linux distros I experimented with).
I don't run Mint here anymore, and I've also stopped running Ubuntu, but both of those have worked out fine for me in the past. Seems to be a lot of hatred here for those two distros, but whatever.
In the end, I simply need to get things done, and no distro is perfect. I don't care if one distro is a little more "polished" than another, or if someone else thinks that one distro is "better" than another. They're all just tools, and I like having many tools available for use. (I don't own only one flat-head screwdriver!)
