6v cells will be easier to handle but you will need many more cables and connections with attendant maintenance to consider.

The big question I would ask is why do you have 2 banks? Everything I know about battery lifespan favours a single bank and the user experience is much more pleasant as well.
I did not design this system, but basically the two banks are connected through a bluesea switch, i think it is a pretty good set up.
One bank is mainly for cranking, the other for "house".
But do i really need 2 x 8D's just for cranking? ofcourse through the blue sea switch, the batts are also partially used for "house" purposes.
