It all comes down to personal preference.
I liked my wet bath in the 22 ft CCD. It IS bigger to shower in. It also has a curtain that pulls inside the door so NO water goes outside unless you get out wet. I'd do a quick squegee down the walls, push the curtain back, wipe towel myself semi dry, WIPE THE SEAT, then step out. Now I always did my hair over the kitchen sink rather than IN the wet bath, just because the humidity lingers even if you leave the fan on. The sink is handy (and at the right height) if you're boondocking and conserving water. Fill, wash, rinse quickly under the shower and you can bathe in less than 2 gallons of water.
My 22 CCD has more wardrobe space than the 25 Safari FB SE - the total space taken by the wet bath is much less than the separate shower/WC sink rooms. And there's more leg room in the wet bath when seated on the throne - also NO sharp edges in the room to bump your knees or bare bottom on. A friend who is disabled noted that she could use the integrated sink as a pull up bar to get up and down from the toilet.
Disadvantages of the wet bath. Occupancy = 1. It needs to be wiped down after every use - at a bare minimum, the toilet and sink surround need to be wiped down. There is no way one person can shave and brush teeth while the other is showering without using either the kitchen sink, campground facilities or the great outdoors.
