I think Port Brewing's Mongo IPA is the most wonderfully unbalanced bitter hoppy beer I've ever had. I've usually had hop matter in the bottle trub. The bitterness is actually quite pleasant.
For aromatic hops, I'd say Boneyard Bone Light. It's pure AROMA/FLAVOR hops, hardly any bitterness, and the malt backbone is so light that the aroma and flavor is overwhelming. I would take it over almost anything else.
