Like you, dependent on the situation, I have different kits that I rely upon. But for the average day in the mountains, I trust my chest rig and small pack. Whatever you use to carry your essentials – make sure you can account for your basic survival needs including: food, fire, water, shelter, first aid, navigation, communication, self defense, maintaining a core body temperature, and hygiene.
