It depends. Can you carry other tools or not? Or is this strictly about knife-related tasks, and which one knife would you choose to accomplish them?
If I can't carry other tools, a saw equipped SAK like a OHT (Longer saw and blade, locking) or a Vic Camper (Second blade) would be my choice.
If I could pack a pocket saw if I felt so inclined, I'd pick a Manix or Opinel 12. The Opinel would have a longer blade which would serve me well with batoning, but the Manix has a sturdier handle assembly and lock.
