According to the product specialist

Pros
The ergonomically shaped shifters are comfortable in the hand.
Logical shifting! Left is rear lighter shifting, right is rear heavier shifting. Pressing both simultaneously makes the front shift.
Fully wireless shifting and therefore easier to mount on the bike.
Great braking performance and control with the Sram Red calipers.
Large gear range with a 2 x 12 set-up.
Uses the same technology as the Ultegra and Dura-Ace shifters.
Battery life: 3.5 to 4 years.
The brake lever is adjustable in reach.
Great shifting performance, high shift speed and smooth shifting while out of the saddle.
Semi-wireless: there is still a cable connection between the battery, front and rear derailleur. Easier mounting and little chance of cable breakage.
You can bleed the brakes without unscrewing the caliper from the frame. Very handy!
With Di2 electronic shifting, you must adjust the derailleurs once and they will adjust themselves automatically in the future.
10% more space between the pistons, reducing the risk of rotor rubbing.
Cons
-
No shift buttons/controls on top of the shifter.
80 grams heavier compared to the Dura Ace R9270 disc brake set.
