IL2 Extension is older and has some instrument readings that the newer one doesnt by default but you can add a lot more. The newer X52pro tool can also control the joystick LEDs based on aircraft warnings and settings.. ie gear up / down - engine overheat etc. Further info available on X52pro tool here including english language translation >

Havent played with the newer one much but they both still work fine in 4.11 and all older versions of IL2 1946. I dont think you can use them both at the same time though!
For IL2 Extension you need to copy directoutput.dll to the correct folder if using Win 7 64bit. I left instructions for this on the last page of the thread i linked to above.
Havent tried anything for CLOD yet as Im not aware there is anything out there for CLOD yet.
