Recessed Cabinet Metal or Plastic?

Hi,

Can anyone offer additional advice on the pro/cons of these recessed cabinets from real world experience?

e.g. is the plastic door rubbish and likely to break off quickly...

Metal: Not great for Wifi, needs earthing, longer lasting

Plastic: Good for wifi, no earthing, might not stand the test of time.
