I've just bought an Push-ed RP23 (only £35 ontop of the RRP), and thought it miles better than the STD one I was using, don't ask me to quantify that though.
Just seems to not be as on/off as the STD pro-pedal, and I've never been one for switching off the pro-pedal, so that makes it even better for me.
You have to specify you weight, bike and how you ride to get it tuned specifically for you, so my tune might not be what you want, but that's no reason to write-it off.
All I can say is that the first ride out, it just seemed mile better, unfortunately my fork has been borked since then so haven't managed much further testing.
Will defintiely be upgrading my other bike's RP23 when I get it serviced.
