I use JSGME, because I've been using it for other games for a long time now (at least 10 years) and I've gotten used to it. It not only helps me keep track of what mods I have installed and the order I installed them, but also which folder applies to which mod. It makes the GameData folder house-keeping much easier to manage, so long as you use it correctly of course. That often means a bit of prepping first before installing the mod, just to make sure everything installs into the correct folder(s).
