Can't comment on the Nissan DIN gauges but the Defi DIN gauges are a much better option for your application since you'd prefer to avoid pillar-mounting gauges, the Defi DIN cluster doesn't need a control unit like the standard Defi gauges do and pillar-mounting gauges generally doesn't look too good from a Legal point of view as opposed to the DIN cluster.
My choice would be the Defi DIN cluster.
