For system-related stuff, python 2 is already 'everywhere', as it's used all over the place for that kind of thing. Even some nodejs modules depend on python for their installation. But if you're going to be doing more than making a standalone script, python 3 should be your target: that's where the maintenance is going to live, and that is where any 'cool_new_module' gets targeted. If you're going to make something big, do it in an area that gets support. I'm not a particularly advanced user of python (seriously, just ops scripts), but it looks like it's basically 'all sticks' to me. I've heard people grateful about better unicode handling, but not much more than that.
