I think you forgot the ultimate reason: ring sealing. Because they are a stronger design, they stay round better, so ring sealing will be better over time and especially on slight overheating occasions.
All aspects had been mentioned why they are stronger, but not what 'stronger' means to operation
A disadvantage (besides cost due to maching) could be that since they are thicker in some places, the cylinder tends to run hotter. In how far the slightly larger fins help there is difficult to determine.
