Here's the pros and cons of handlebars
1. Big Handlebars
More precise control
More leverage against ruts and rough terrain
Slower to respond on quick turns
Stick out and catch brush in the forest
2. Smaller bars
Quick to turn in tight corners
Compact in thick scrub
Less leverage available against ruts and rough ground
Therefore - less precise steering in rough terrain.
Given the above, choose a set of bars that match your size, strength, preferred riding posture and usual riding conditions.
