Between those choices, it's mostly personal preference. In many situations, but not all, traction comes down to the size of the contact patch. How many square inches of tire are gripping the road, dirt, sand, rock, etc. Most if the time, more is better. That's why we reduce air pressure in the tires when going offroad. It allows the tire to squish and have a bigger contact patch. In sand, the bigger contact patch reduces the weight per square inch of contact so you don't sink in as easily. I believebthe same idea is used for snow. On rocks, it allows the tires to conform to irregular surfaces and grip better. However, at high speeds, on pavement, the bigger contact patch will hydroplane easier, especially when the rread wears down and can't channel water away as easily. Year's ago, someone explained to me that in shallow or medium depth mud, a skinnier tire with smaller contact patch was better because the tire could dig to the bottom and find firmer material to grab. I ran 33/8.50 r15 mid terrains on my F150 back then and liked them. But lots of. People will say you want big tires in mid for the flotation. I won't argue that either way. It depends on the situation.
So, find a tire you like in a size that fits your truck and your budget. The good/bad thing about tires is that they wear out and you get to buy something different next time if you don't like what you chose this time.
