I would use Pyib if it came with an oekaki function. that's basically the only reason I ever used kusaba (upload boards were also liked,but can be done with normal imageboardsanyway.)
But yeah, the kusaba continuations have done nothing but have a huge pissing contest when out of the 3 of them, only 2 have working code and they are both basically useless. Extra embed functionality isn't really anything major, when you think about it.
