According to the product specialist

Pros
Due to the improved heat dissipation, the braking performance at heat is very good.
This disc is very wear-resistant due to the use of harder metal than in cheaper variants.
This disc makes your bike a lot more beautiful.
The heat dissipation of this brake disc is very good by Shimano's Ice-Technology Freeza.
Due to the harder material, this brake disc can also be used with Semi-Metallic and metallic brake pads.
This brake disc is made of light materials and therefore has a low weight.
You can choose different sizes of locking rings with this brake disc, so you don't have to buy extra lock rings with a 15 mm through-axle.
These brake discs deform relatively little when heated, and are therefore less likely to seize.
Low weight disc brake.
Great braking power, superb heat dissipation.
The disc brake is easy to mount yourself.
Your bike will look better with this awesome disc brake!
Cons
This Ultegra brake disc is heavier than the Dura-Ace version.
This brake disc is slightly heavier than the XTR MT-900 brake disc.
Not available with 6 bolt mount.
