"Comfort ratio" is a calculation that does not actually reflect how a boat really behaves in bouncy situations. It sounds more comforting than it actually is. Hull shape, which has a big impact on pitching, yawing, and heeling, is not part of the equation. Ted Brewer, who cooked it up, notes that it is for comparing SIMILAR hull types. The boats on your list are not all similar hull types. Ted Brewer Yacht Design
If you like boats that perform well in windy situations and need an enclosed head, J/30's should be on your list as well. J/29's might be a bit quicker, but on the J/30 it is nice to be able to stand up down below.
