For my level, I personally found the Bee shrimp is the most difficult to keep and breed. Personally, I am managed to breed once in temperature 24C. CRS is almost the same like Bee.

Cherry, Malayan, Tiger are easy to keep and breed. Yamato are easy to keep. But breeding it and you need more knowledge about how to grow the yamato larvae in salt water and the salinity level is important to grow the larvae. Which is the same like Red Nose and Mosquito shrimp.
