According to the formula by Delerious, the comfort ration is based on three values: LOA, LWL, DISP, and BEAM. The four boat you list are very close in LOA and Beam. That means the main cause of the different values are Displacement and LWL. All else being equal, a boat with a higher displacement is slower, but has a better motion. All else being equal, a boat with a shorter water line is slower. I think the better motion in this case is probably more controversial.
In any case, all of these are quite heavy boats that have moderate numbers in other areas. They will all be comfortable. I would focus far less on the motion comfort ratio than other factors when comparing these boats. Other factors that I think are more important when comparing these four boats are build quality and function of deck, cockpit, and cabin layout (you will have to tour all four do decide this).
Even more important: which of these boats makes your heart sing when you look at it? They are all great boats, but the one that takes your breath away is the right one for you.
