I did a lot of tests with different modem versions in order to see battery usage impact with my current configuration (Touch X v2 + ninphetamine 2.1.3).
To do those tests easilly and day after day with same situations, I used a CWM script (zip file) to avoid PC / Odin.
Here is those different modem versions with script :

For those who want to backup their modem before any flash, here is a CWM script I just made : HERE
Very quick user guide :
1/ download zip file and put it onto your internal sdcard
2/ if you have CWM app installed, you can use "Flash update" and select the zip file. Else reboot in CWM and use "install from zip".
No wipe needed

Maybe someone more experienced than me could have a look into the modifications done by THREE to this modem and apply them on other versions...
Attached as a zip package flashable through CWM.
This is NOT the regular KF2 that you can find all over XDA, its extracted from my stock 3UK Rom, its modified by Three to serve their network better, and I can say they have done a good job.
Once again this is NOT the regular KF2 Modem

3G usage (stream radio), screen-off :
KG6 (13%/h) < KG5 (14%/h) < KI3 et KI4 (15%/h) < KG2 et KI1 (16%/h) < KE4 et KF2 (18%/h)
Here is performance tests I did those last days (around 200) using versatile speedtest.net (so many possible issues) :

SpeedTest.net is a little bit complicated because we have a lot of infra between our GS2 and the server. So, we can have day after day, test after test, different results.
My approach is to bench a lot and provide a MIN/AVERAGE/MAX for each modem.
After that, my choice will be based on average battery usage.
All of this hard work is to provide a single view of what we can expect but, of course, because of so many networks, this is a little bit limited

My idea is to give a way to avoid Odin/PC and to decorrelate ROM and modem versions.
Moreover, I am trying to investigate battery usage for each in some situations. I am not paying too much attention on network efficiency.
