OK I'll try to answer directly, from one noob to another.

Good: most Navy flakes, C&D Pirate Kake, Dunhill 965, Sutliff Sweet Virginia
Bad: OTC, most stuff you see in big jars at the B&M, blends that are predominantly cavendish.

Taste in cigars is pretty subjective, but IMHO tastes in pipe tobacco is even more so.
