I've never liked Jefferson Airplane desu. They had some first-rate musicians, but their lyrics always felt uninformed, preachy, and over-the-top. A lot of my parents' generation picked up some pretty stupid/destructive ideas from them, and their music has aged like dirt.
That leaves Jefferson Starship, who did some fine pop hits in the late 70's, the underrated Blows Against the Empire, and a trio of superb melodic rock efforts once Mickey Thomas joined (prior to the Starship years). So I'll go with them.
