Which legion is a "good" shooty army, and what models support this? Dreadnought, tanks?

I really like all the legions designs, I can't decide which one. But I definitely want a more shooty army as my 40k army is dark angels with a melee focus.

Also, what should I do with my age of darkness box when it arrives, load out wise?

I have a box of special weapons. A command squad. A Dreadnought, the one with missiles on its back. And a support predator.

None built yet. I still need to get either the traitor or loyalist books.

Any help or direction would be appreciated:)
