Broadsides come with a built in defense option called drones. THey also have a lot more firepower. Not really comparable. I don't consider it a whine to point out a unit may be overcosted and not very useful in an army. Every codex has point losers and point winners. Considering the general blaise opinion of the model's appearance the usage of the model will depend solely on its utility. So far the Rumors are making them sound a bit weak and overcosted. Final print will let us know how useful they will really be. Right now with the information supplied I am finding a hard time working the 180+ point unit into my army list.
