I think you know its not just a matter of "clicking a setting in a gui once"
I know it is that simple because I've done it while running MX on my devices... You can even switch between the two at boot freely.
Why would you choose a non systemd based distro only to just switch it over to systemd? Why over complicate thinga for a new user who is clearly just starting out? Just use normal debian!
It comes with tools that make system management a lot easier for beginners. I think that's more than a fair trade for having to click a single setting in a gui.
You obviously haven't used MX, and I have no clue where you're pulling your opinions out of from. Give it a try instead of continuing to spew nonsense.
They're also far more enjoyable for walking.
Strolling down grid roads with gigantic buildings feels like you're getting nowhere. Absolutely mind numbing.
