I don't think I'm missing anything from S2 either, aside from the ep where Q introduced humanity to the Borg. Hypothetically, if someone is new to the series, I suggest they watch s1's best: Heart of Glory, Datalore, Arsenal of Freedom, Where No One Has Gone Before, 11001001, all Q episodes, along with the pilot to get a taste of who the characters are, their backgrounds. Then watch Q Who? and then jump into S3.
Of course, I plan on watching all of S2 when it drops on blu ray.
Also, TNG quality is not up to Riker's beard because he has a beard in s2, but their uniforms. S3 uniforms have collars, aren't skin tight, and Troi wears a new uniform every episode to tease your dick with.
