I've had the Favero Assioma Duo pedals for over 4 years and while they were excellent I was always annoyed at having to switch to the Look Keo cleats. I was tempted when the Duo Shi version came out but really didn't want the additional Q-factor when my fit was already dialled in. So I was excited when the Pro RS-2 pedals were announced, with all the improvements, in a more compact pedal .. which weighs less than a regular Ultegra pedal! The pedals were easy to install with the Favero app, and once new SPD_SL cleats were setup they were perfect. Much easier to clip into and the data was just as consistent as I expected. Now with the extra PCO info as well. While they're not cheap, they're the lightest SPD-SL pedals around and >£100 cheaper than the Germin pedals. If you want amazing PM pedals these are the ones to get!
