According to the product specialist

Pros
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.
Reliable groupset with a similar level of performance to the Shimano Ultegra R8020 groupset.
Fast shifting and powerful braking.
The front derailleur has a cable tensioner for easy installation.
The crankset is wide and therefore extra stiff to optimise your power transmission.
The rear derailleur with Shadow technology prevents external impacts, due to its clever alignment under the cassette.
The Shimano GRX RX810 groupset is a versatile, high-performance groupset for the demanding gravel rider!
The hydraulic heat-dissipating disc brakes with Servo Wave technology give you more than enough braking power for even the steepest descents.
This GRX groupset is optimised for wider gravel tyres and bumpy terrain!
Cons
These calipers don't have the 10% extra clearance that the new Ultegra R8100 calipers have, so your brake discs may rub slightly.
This Shimano 105 group is a bit heavier than a Shimano Ultegra groupset.
Because of the clutch, the chain tension is higher, which increases mechanical resistance.
