Bjung, that is obvious
You have to chose if you want the extra performance and stability or the bigger flexibility of a swing keel in what regards recoil if it hits the bottom.
Anyway on a voyage boat with a big draft on a lifting keel like the Atlantic 43 you can cross the Ocean with the big draft on and when approaching the coast looking for an anchorage you can pull it up. Maybe you have to reef for safety but given the big hull form stability and the huge ballast you can still sail with the bulb up on that boat.
A bigger disadvantage is that a lifting keel on a relatively small boat is not only more expensive as has more implications and limitations on the interior design of the boat. That's why almost all small boats that have ballasted keels with variable draft use swing keels. Normally only boats with 50ft and over use lifting keels. The Atlantic 43 with a lifting keel is a really expensive boat, much more than a Allures 45 for instance and probably more than a Pogo 50 or a Southerly 42.
