Friend bomber vs Facebook marketing GI vs Facedominator?

Which one do you think is the best bot for facebook marketing? To be honest, it's quite frustrate to invest in the software, if in the case of instagram, we will just go straight to followliker but facebook is not that simple so what's your idea?

Friend bomber or Facebook marketing GI or Facedominator

Any suggestion will be appreciate
Thanks you all

I will like to see some answers to that too. got a couple of ideas in mind for 2016 with fb, and was thinking about massplanner

I'll go for FBMarketingGI since i already tested it. They update the software almost everyday.
