This, today could be an interesting subject. With the modern diesel actually burning cleaner than a gas engine the emission's argument is out the window so anyone who supports gas because of emissions has no argument.
HP ratings: if the gas and diesel engine and both produce the same HP and torque one will not out pull the other. HP is HP, don't care if it's gas. diesel or steam. The same goes for torque.
So it boils down to cost to run and maintenance.
With EFI and EI there isn't much maintenance to do on a gasser other than oil and filters. On cars and trucks some have tune up intervals of 100,000K with 7,500 miles oil changes. If they still built 100HP tractors in gas you wouldn't really have any more maintenance to do over the diesel. Think of it, the modern gas engine is good for 200,000 miles or more. In that 200,000 miles there is one tune up (why do the 2nd if yer only going to run it 200,000). The one down side to gas would be engine life. While diesels can run 10,000 hours or more a gasser would, at todays build standards run about 1/2 that. But gas engines are generally under 1/2 the rebuild cost of a diesel.
A gas engine to diesel upgrade for a new pickup is about 8500 bucks. Id' bet the gas tractor would not have the same disparity at first because diesel today is the norm and the gasser would be to odd one. So the next consideration would be fuel consumption. Most of your older tractors around 100HP that were available in both fuels the gasser would burn about a gallon an hour more than the diesel. Back then diesel was about 2/3rds the cost of gas. So the only advantage of gas was initial purchase price. Today, diesel is higher than gas plus due to computers, injection and IE gas engine are more efficient. Back in the day the gas engine in general was about 60% efficient compared to about 80% for a non-turbo diesel. Today the gas engine is bumping that same 80% mark. So the big question is how 2 identical tractors at say 100HP, 1 gas and 1 diesel would compare today in fuel consumption. Would the diesel still be cheaper to run over 10,000 compared to the gasser?

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
