According to the product specialist

Pros
The Shimano GRX RX8255 Di2 12 speed groupset is a complete, high-end electronic groupset for gravel bikes.
This groupset's shifters feature a third Di2 button to operate your bike lights, computer or other devices.
The ergonomic design of the GRX RX825 shifters fits handlebars with a flare design and reduces hand strain, increasing your control on uneven terrain.
The rear derailleur is outfitted with the Shadow RD+ system for quiet and precise shifting, which also allows you to easily remove your rear wheel.
The hydraulic disc brakes are specifically tailored for gravel and off-road use, so you can count on precise and efficient brake performance no matter the circumstances.
The gravel-oriented Sram Apex XPLR 1x12 shifts wirelessly, quickly and smoothly.
SRAM Apex AXS disc brakes give you smooth, powerful hydraulic braking.
A single front chainring, 12 speeds and a wide range of gears are an unbeatable combination on any terrain.
The crankset has X-SYNC direct-mount chainrings for good chain guidance.
The rear derailleur keeps the chain under tension and prevents it from chattering.
Cons
The new Shimano GRX RX825 is only available as 2X version.
Apex is heavier than the more expensive Force or Red XPLR.
