I know that there are so, so, so many variable that come into play when discussing stumps that I won't touch that. But with a combination of soft wood, hard wood, different soils, sizes from small up to 36", etc. etc- at the end of the day with the same operator will there be much advantage in a 24 ton vs. a 20 ton? If renting, is it worth the extra $$$ to go with the larger machine?
