The Il Cannone G strings are designed to partner and support the other strings in the set, especially the new C strings. In comparison to the popular Magnacore G strings, the Il Cannone G variants solve one issue: there is no potential metallic sound when playing open strings, the sound is uniform across all positions.
Another difference to the Magnacore G is the flexible construction of the Il Cannone G. This provides easier playability and a faster response. However, players preferring the resistance of a string to bow and finger will probably prefer the Magnacore G and observe them to be faster in response. Again, Il Cannone is a great and versatile add-on to our portfolio and not necessarily a better replacement.
