I would say that it depends on the application. The CM9 and the R52 use different generation of Atheros chipset. The main difference between the 2 chipsets is the newer chipset requires slightly less power to run and if you are running the card in 10MHz or 5MHz modes it will only listern to that 10MHz or 5MHz whilst the older CM9 chipset will still listen to the whole 20MHz.
If you are looking to replace a 200mw 2.4 card then both the CM9 and the R52 may leave some of your clients with a weak signal so the Atheros based 200mw cards would be the way to go. If you aren’t looking to use 10MHz or 5mhz then the CM9 is still a great choice however there are a couple of other next generation Atheros based cards out there.

I am looking to replace my current APs and have decided to
move to Mikrotik but am not sure of the best choice for a radio. The ones I am contemplating
are the CM-9, R52, or the WLM54G. I currently use CM-9’s in 5.8 for my
backhauls and so far have been satisfied. My current AP radios are 200mW Prism
radios (2.4), so I was considering the WLM54G as a replacement. The concern
with them is a lot of resellers are out of stock, plus I have heard a few
people say they have had performance issues with them. Lastly I have seen the
R52, seems similar to the CM-9. The only issue I have with it so far is there
