On one hand, SoFo is pretty cool since it completes gravity as a control based element (a variety of flexible CC, PC protection, damage redirection, shield bypass, quanta control, a shield that is made to be coupled with CC and, with the shard, PC). On the other Zanz was probably drunk when he balanced it. I'm actually divided between Elite Chargers and Overdrive, for their usefulness and Dilgos, for being cool looking.
