Prior to purchasing our 'C' we rented 'C's on and off for a number of years. We had lengths from 24 to 32 feet, slide-out and non-slide-out. Safari, Freelander, Sunseeker, Tioga, probably others were all represented.
What we found was the non-slide-out 'C's had too little floor space in front. Rear corner beds were ok, the biggest issue with rear corner beds was having to crawl on your knees across the bed to access the cabinets above the bed. Longer 'C's with the rear platform bed also had the same issue, accessing the cabinets above the bed.
We saw a 26' footer as being the best size, reasonably maneuverable, yet sufficient room, but with a corner bed.
What we settled on was a dual-slide C, 28' with a rear walk-around bed. It has a roomy rear wardrobe so direct access to drawers and cabinet. The lowest drawers are blocked in when the rear slide is in however. Having the rear separate bedroom is great for when one of us wants to stay up late and the other doesn't. Or when we were out over New Years and I caught the flu and was knocked out for a couple of days.
Here's the floor plan:
