Perhaps if the question was framed around ‘Better Leaders’ and ‘Better Soldiers’? By recognising that there is a difference between the two.
Some very excellent soldiers may shy away from becoming leaders.
Can it be that a unit commander leading his men in combat is less aware of his fear because he is so busy dealing with his responsibilites i.e. leading his men effectively and achieving his mission? The men, on the other hand, have plenty of time to focus on their fears. I think someone already mentioned motivation, it can’t be ignored.
One officer I once new, serving with a Cumbrian regiment, commented that countrymen make the better soldiers as they are at one with the countryside. Another one from a different regiment swore that, in his regiment, the men from the back streets of Manchester and Salford made the better soldiers, as they were used to sneaking about at night stealing lead from the rooftops of wharehouses, churches and the like…"…excellent training for night patrolling!.."
Another one once told me that the men of the Durham Light Infantry were the better soldiers as they were usually ex-miners and were tough, gritty and accustomed to being in deadly situations.
All sweeping generalisations.
