According to the product specialist

Pros
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.
Great shifting performance: quick and smooth shifting even when you're standing on the pedals.
Amazing modulated braking power without abrupt clamping of the brakes.
Semi-wireless: there's only a cable connection between the battery, front and rear derailleur. This makes for easier mounting and a low chance of cable breakages.
You can bleed the brakes without unscrewing the caliper from the frame. Pretty convenient!
The derailleurs only need to be finetuned once thanks to Di2 electronic shifting. After that, you'll be ready 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.
Cons
Dura Ace comes at a much higher price than the Ultegra and will not be affordable to all.
Ultegra R8100 Di2 Disc is not the most lightweight groupset, and is heavier than Shimano Dura Ace R9200 Di2 Disc.
The Shimano 105 R7100 Di2 Disc groupset uses relatively heavy materials in its components. This is reflected in the total weight of the groupset.
