The KIng Crab I received has 6! arm mounted ballistic hard points ... 2 energy, 2 missile and an AMS. One of the other KIng crabs appears to have 2 ballistic, 4 energy and 4 missile. The frontal profile on a King Crab looks to be a bit smaller than an Atlas ... hard to say for sure since it might be lower and wider. Otherwise they start off with basically the same armor and structure.
The KIng Crab would seem to have greater choice in loadouts and more devastating loadouts.
Unless the KIng Crab hit boxes somehow make it much more vulnerable than an Atlas ... why would I ever drive one of my Atlas' over the King Crab?
(Not a troll ... I am actually curious since the King Crab at least appears to be strictly better than an Atlas ... not sure yet how it compares to a Dire Wolf though I think the DW still has the edge since 6 CUAC5 and similar builds are hard to beat ... though the King Crab can do 2xGauss + 2xERPPC for lots of PPFLD fun ... if you can get the coordination correct)
