Hi, 
I could not find a comparative study which reports the difference between the two modules in terms of wireless transmission. Since the two modules are mostly similar, the difference in power consumption and range would be because of the wireless technologies they are using.

Please report the differences primarily for:
1. Power consumption overall
2. Power consumption during wireless transmission
3. Approx. Range (LOS and NLOS)
4. Ease of development
5. Any other important factors.

Thanks a lot :)
