First and foremost the Napoli was a
very fast ship. The first of the class to be finished was complted in 1907, the year before the British completed the world's first battle-cruiser. That makes the Napoli a sort of pre-dreadnought battle-cruiser.
Also the arcs of fire are excellent. Two turrets for main armament was pretty standard pre-dreadnought practice, but to also place the secondary armament in turrets was advanced. Those secondary turrets also being arranged very well, to give 8-gun end on fire, as well as the standard 6-gun broadside that casements would give. Casemented secondary armament would only give 2 or 4-gun end on fire depending on the layout. The centre turrets have clear 180 degree arcs, which is excellent.
The trade off is that the main turrets only had one gun each, rather than two. But then, no ship is perfect.

what happened to the Italian fleet by WWII?
Italy started WWII with an excellent fleet of modernised WWI battleships and new battleships. What happened to it was
Taranto. Nobody had ever launched an attack like it before (it probably helped inspire the Japanese to Pearl Harbour) and the Italians were not expecting it. Overnight they lost their advantage in the Mediterranean to the British.
The importance of those few torpedo-bombers that launched the Taranto attack should not be underestimated. Had the Italian fleet been able to effectively block the British convoy routes it would have been a disaster for the British in North Africa, and the hypothetically the possible loss of the Middle East, which would have been a disaster for all the Allies.
