According to the product specialist

Pros
This groupset was specifically developed for off-road use.
The chain always stays tight because of the narrow-wide designed chainring and the rear derailleur with clutch.
The shifters and calipers are specifically designed for off-road use.
The Shimano groupset with the best value for money.
This groupset combines smooth shifting performance with good braking performance.
Mechanical shifting with this R8020 groupset is smooth, even under load.
The chain and cassette have an extra coating to improve durability.
Top material to finish a top road bike with.
The wide range of this 12 speed groupset is well suited to all surfaces and environments.
No more chain slap thanks to to the innovative Fluid Clutch.
You can customise this groupset to your preference.
The groupset has many of the properties of the pricier Red AXS.
You can switch the parts of the groupset with SRAM Red and SRAM Eagle AXS parts.
Cons
Due to the 1x11 drive system, the gears are more staggered than with a 2x11 drive system.
These calipers don't have the 10% extra clearance that the new Ultegra R8100 calipers have, so your brake discs may rub slightly.
Cheaper materials make this groupset heavier than the Red AXS groupset.
You need a special XDR body on your wheel to mount this cassette.
