We looked exhaustively at RVs in general...from pull-behind travel trailers to toy haulers to 5th wheels to A and C class motorhomes. We had settled on a Class A for many of the reasons stated above. Honestly, many of the Class A units are designed for only 2 people even though they have additional sleeping capacity. After deciding on a Class A, we had a used one in great shape basically fall into our laps. We love it and I doubt very seriously that we will ever look back.
Ultimately, it's what you want to do with it. As suggested, go to shows and to RV sales lots and just look around. Take both for a test drive and see for yourself. I actually think the Class C drives better (more like a bigger pickup truck or van than a bus) than the A, but you may well think the opposite. It took me no time to get used to driving our Class A. Get comfortable with the floor plan and interior amenities on whatever you choose because you're going to spend more time enjoying that, than you will driving it. And, as also pointed out, you can rent first to try it on for size.....but that's not cheap either.
Good luck with your search!!
