No i dont know the actual depth difference but i will say i havent ever used mono or braid for cranking i have always used flouro simply for the fact that it does sink and it helps your bait dive deeper. Im sure it doesnt have the sensitivity that braid does and also majority of the time im fishing really clear water which is another reason i prefer flouro. In your case with the water being muddy it shouldnt really matter unless your deep cranking to use braid. Thats jmo though hope it helps.
