Is a neuro surgeon or spine surgeon better equipped to do cervical spinal decompression?

Both able to. Neurosurgeons are spine surgeons by nature and receive training in spine surgery throughout their residency. Orthopedic spine surgeons generally do not get as much spine surgery training in residency, however they complete a spine surgery fellowship after residency. It ultimately comes down to the individual surgeon and how comfortable you are with them and he/she is with particular procedure. .
Either. Make appointments with both, see how you like them. Both can do fellowships in spine surgery.
