Well... I thought a few of our members would have some suggestions, but they must be recovering from their fireworks festivities.
In the 45 foot range, the boats you've mentioned pack a lot of features in the mid-size range. Personally I like the new 390 Sea Ray. It's reminiscent of the old Chris Craft Connies, but with a futuristic flair.
With twin Cummins diesels, it'll top 30 knots, but achieves the best mileage around 20 knots. It's a little heavy at 26,500 lbs, but it's built well and draws on much of the same technology that has made their Express Series so popular.
Sea Ray has managed to provide a lot of headroom inside the 390. Another option I particularly like is an air conditioned bridge, which you would seriously appreciate in South Florida's prolonged idle speed zones during summer.
The things I take into consideration are not items visible to the eye. They are in the engineering before construction. For example, the molds that are used to make a Sea Ray are made from a foam plug that is cut on a CNC to tolerances that approach thousand's of an inch over a 50 foot plug. This is almost impossible to achieve in hand carved plugs.
But before the router touches the foam, the entire hull, deck and inner liner has been constructed virtually, resulting in a seamless integration of what is sometimes... sub-components with some manufacturers. Personally, I find Sea Ray's ergonomics well conceived. About the only drawback to the 390 Motor Yacht is the lack of a flybridge, which is offered on the other models you mentioned.
There's a lot of great choices in this range. Many of them, I've not had the opportunity of boarding, but because I've sea-trialed this particular yacht (and you mentioned it), I thought I would share my experience.
I hope we can get others to chime-in on this thread with some sea-worthy suggestions.
Here's a picture of the 390...
