I have seen the Fire Extinhuisher M being used very often. Never seen nor used that Armor.

Generally speaking, a part which requires more slots is better (see Engine Nozzle S, M and L), but as I have wrote aboute the Extinguisher M requires less slot than the Armor.

Another big exception is the Data-Link Antenna, which requires only 9 slots with a Cst=40 value.
