Let me take an offbeat, unusual, personal stab at that based upon memory:
Batsto; Tight, dark, primitive, historical. The river less traveled.
Mullica: Traffic jam on some days. A well-traveled River. Long, long. Beloved.
Wading: Ditto to the Mullica. More twisty, more deciduous. Gangs of teens.
Oswego: The jewel of the Pines if you catch it just right. Cedar-lined, tempermental. Clean.
Rancocas: Stately, ancient. Dark amber. Many choices, but is swallowed by civilization in the end.
Cedar: Crystal depths, unsullied. Less discovered, less traveled. Longer than seems on the map.
