I have been using Manjaro for quite a while now. In fact I have three computers two of which have Manjaro and the third has ArchBang.
I am thinking of replacing Manjaro simply to get away from systemd. I am currently in the process of repalcing systemd on the ArchBang laptop. If it works, I'll do the same with Manjaro if not I'll replace Manjaro with a systemd free distro like Void.
Void might be the way to go, ArchBang can be converted too run systemd free but keeping it that way (and working!) might be an uphill struggle. Take a look at obarun (on these forums) or possibly Alpinelinux (personal choice). Did have an iso based on Voidlinux called Sprinlinux but Void's developer got a little upset so we decided to drop the idea.
Welcome too ArchBang
