Agreed about the MG34 being better than the MG42 (aside from timing), it has better and faster veterancy, it reacts faster, it suppresses just as quick and costs less. It does less damage, but is arguably supported by more reliable infantry. I'd still pick the MG42 over the Vickers or Maxim though.
I totally agree. MG34 is somehow more reliable imo and suppresses a bit faster than the 42 for some reason. Plus it gets a RA bonus at vet 4 (1.25 to 1, I believe) which is very useful which other mgs don't get.
