According to the product specialist

Pros
Mounting is easy.
6x stronger signal, so reduces the risk of interference
Cadence measurable through magnet.
This power meter provides reliable results and has a low deviation percentage of 1.5%.
This powermeter fits all Shimano Hollowtech II Race cranksets.
This power meter has a high water resistance rating and is resistant to extreme conditions!
With ANT+ and Bluetooth connectivity, this power meter can be paired with virtually any cycling computer.
Mounting this powermeter is very easy.
The AA battery in this power meter lasts very long and is easy to replace if needed.
The crank is very rigid and light.
You can choose the set-up.
You don't need a magnet for the cadence measurement.
Compatible with Shimano SPD-SL cleats.
The Garmin Rally RS measures advanced data, including power and performance analysis, cadence and left-right balance.
The sensor shaft can be transferred to other versions of the Rally (XC or RK) and Vector 3 pedals.
Full integration with the Garmin Ecosystem, including Garmin Connect, Edge cycling computers and Garmin sports watches.
Available in a single-sided version and a double-sided version for the most advanced and accurate measurements.
Cons
Single-sided measurement doesn't give the complete picture of your effort.
This meter only looks nice at a Dura-Ace R9100 crankset.
A single-sided power meter is less accurate than a dual-sided power meter.
If you mount this power meter on a 105 R7000 or Dura-Ace R9100 crank, the colour will differ.
The measurement is one sided giving a less exact representation of total power than a double sided power meter.
Has no internal battery, so you will need to replace the button cell batteries from time to time.
