Aicon 56 seems well built, but has small galley and flybridge, and v small saloon (more like a bus stop). Pearl 60 has small flybridge, and looks too busy for my liking, but that's personal choice of course.
Both have lots of big comfortable cabin space, so I guess this is important to you. The Pearl aft cabin is fab and super quiet at anchor, which is a big plus.
IMO you can now get similar cabin space in boats that don't have the same compromises on size of the saloon and flybridge, eg Azimut 58, Princess 54/58, Manhattan 50/60, new Sq 54, Sealine T50/60, Ferretti 510/592, etc.
