I have no experience on the 55's, but have run several 48's. Theyre well built and well thought out. The owners of the 4 boats I dealt with over the years have loved them. They can be a little wet, and their design does not lend them a ton of interior room compared to other boats that size. They seem to handle well in a sea, but I've only run them each for a day, not a delivery. Keep a varnish brush handy.
