How do yo accidentally wipe a hard drive? I hope you didn't loose anything important.
Also as someone that's been using dwm for just over a year, don't bother with tiling window managers for machines (or users) that you don't plan to do work with.

As far as systemd goes, I don't really have strong opinions, but most of my machines (excluding desktop) run systemd and there doesn't seem to be issues. I do think other init systems are easier to understand, and are easier to fix when problems arise however.
It just blows that pulseaudio doesn't work without it, ALSA is good, but if you want to record stuff you have to play around with jack and ALSA loopback devices which is a huge pain ._.
