Not to mention that by virtue of 6 men crews and faster pack-up/set up ie. the Maxim is harder to flank and to wipe than is ie. the 42.
Deathloop says your wrong. Fix that and maybe. Also they maybe faster but it has to be with the narrow cone of fire. Much easier to flank then the MG42. I have seen triple MG42 used effectively in aggressive play with an engineer spotter to completely pin split units. Hard to flank over 200 degrees of overlapping MG fire.
