Longbeards with Great Weapons or Hammerers?

[Scipio]

Fighting mainly chaos at the moment was wondering which of these two units were better to bring in terms of an anti-armour unit?

As general principles go, I also choose the great weapons when dealing with chaos. Great weapon quarrelers, miners, etc. I do find Hammers to be weaker to artillery fire and just a more squishy unit overall in comparison to longbeards. Do note though that I have not used hammers against chaos yet, only against greenskins and two human factions

Hammerers are weaker than intended. They currently have no reasons to be picked in a dwarf army.
Front line should be longbeard+ironbreakers

Hammerers. Longbeards with Great Weapons are the "lower" tier version.
