According to the product specialist

Pros
This groupset is 100% complete and includes absolutely everything you need!
High shifting speed and precision, even when you are stepping down on the pedals.
Semi-wireless: there's only a cable connection between the battery, front and rear derailleurs. This makes mounting easier and cable breakage highly unlikely.
Braking power with superb modulation and smooth engagement. For brake bleeding, the caliper must not be unscrewed from the frame. How convenient is that!
The derailleurs only need to be finetuned once thanks to Di2 electronic shifting. After that, it's done for the rest of your road bike's life.
Precise shifting performance and high speed shifting, even when standing on the pedals.
The brake lever is adjustable and the rotors are less prone to rubbing, improving your control while braking.
Semi-wireless, with only one cable between the battery, front and rear derailleur. Easy to install and low risk of cable failure.
You can bleed the brakes without dismounting the caliper from the frame. Pretty convenient!
You'll only need to position your derailleurs once, and then you're ready for the rest of your road bike's life. The shifters' battery life lasts an impressive 3 years.
-
Unrivalled shifting performance in terms of speed and shifting under load.
Powerful braking and improved control to prevent sudden gripping of the brakes.
Semi-wireless, no more cables between the shifters and front derailleur. Easier mounting and less chance of cable breakage.
You can bleed the brakes without unscrewing the caliper from the frame. A time saver!
One time only positioning of the derailleurs and you are ready for the rest of your road bike's life.
Cons
Ultegra R8100 Di2 Disc is not the lightest groupset; it is heavier than groups from a higher segment.
The Shimano 105 R7100 Di2 Disc groupset uses relatively heavy materials in its components. This is reflected in the total weight of the groupset.
-
Dura Ace comes at a much higher price than the Ultegra and will not be affordable to all.
