The idea of these polls is to compare two similar Chaos Dwarf units head to head. The units may be similar in terms of function, unit type, battlefield roll, etc. The objective is to compare the units in terms of game play performance. So try not to include aesthetic, lore/fluff or model preferences in your decision. Simply which of the two units would you most often choose if you were building a competitive list?
Chaos Dwarf Infernal Guard vs. Hobgoblin Cutthroats
Other than being core choices and infantry these units are about as different as can be. Elite vs. cheap. Sturdy vs. numerous. Since they are the only core choices available to the LoA, I think it makes for an apt comparison. Choose the best/preferred setup for both units and compare! Try not to include Ironsworn in your comparison as they are not a core choice, but all other Infernal Guard options are fair game!
