While average kick distance is an important consideration, I think that "Net punting" average is much more important as is average hang time and numbers of punts inside the 10 yard line as well as number of return yards and punts blocked. Punter does not get all the credit nor blame when the Net punt yards are not as good but a great punter will normally have superior numbers in these areas as he has the skill to place the punts in the right locations and not just boom them down field a bunch of yards. And long punts which are fielded and returned will often be big returns for the opponent. What you of course really want is a punter who will flip the field position and put the opponent's offense pinned against its own goal line or in a tough position relatively speaking. The punter has to help his defense and his offense. Field position is his contribution area no doubt. Compare those numbers and then you can really discuss which punter may be better. But, one needs to be careful. As with most statistical comparisons, I feel it is best to toss out the highest 2% and lowest 2% of the data and then compute the averages, etc. This eliminates those odd instances which can really distort the numbers.
Both these guys, along with a dozen or more others, are and were excellent punters. Nebraska has rarely if ever had a 'poor' punter and typically has a punter in the top two or three in the conference. This has been the case for decades.
