There is talk about debian moving from init, so LMDE may move.
I had more problems with init because of daemons not starting leading to the whole boot process halting.
Also, start-up with systemd in Arch is around 15 seconds for me, where startup in Mint is much longer (at least double that of Arch on the same hardware, or so it feels).
Problems? Tell us EXACTLY what you've done and what you expected to happen, IN DETAIL. That will save us questions, and we should get along better,
I have dysgraphia. This means I might have understood you incorrectly through no fault of my own.
