I have tried a bunch of smaller Busse's and worked around the choil/talon hole/guard and they work great, stay sharp, get the job done and you NEVER doubt you have a quality tool in the hand. I have had a Euro 4, Meaner Streets, Active Duties, BA-E and Game Wardens. The GW offends the least in this regard and I kept two of them. If I wanted one that bad I would find a way.
For me though... at the margin... when your leather gloves are soaking wet, it's you are in freezing rain or sleet and you are trying to start a fire you want to be using tools that HELP you engage in fine motor tasks because you may be shivering like hell. Having your edge close to your index is just easier to be more controlled.
Having your index finger 1 1/2" from the edge and your thumb over the ricasso does not aid in leverage on your work.
People will argue that but I used to carve objects out of wood that people were willing to pay a lot of money for. I have carved a LOT. Everyone is entitled to and will have their opinion though.
