From what you describe you're looking for, I think a Low Rider would be a perfect fit. As already suggested, a test ride will confirm this. I've never ridden a Fatboy, but the general consensus is that a Dyna will handle better. The Fatboy may be fine for you however.
The 'Dyna Death Wobble' you mentioned is a reference to the fact that the drivetrain is rubbermounted and when leaning through a high speed curve sometime they have a tendancy to wobble. Can be fixed easily for a couple hundred dollars.
I ride freeways, as well as narrow highways with moderate twisties, and city riding. So being able to maneuver is important. My Sportster is great for this and after 15 months of riding it I can thread a needle with it. I want a bike that is similarly maneuverable.
With what you stated above, the Low Rider would be the clear choice IMO. The Low Rider is very much like a bigger Sportster on steroids with that 103" engine. So it should feel like a natural progression to you.
I had an 06 1200 Sporty that I sold to get my FXR about 1.5 years ago, so I can relate to the agility and maneuverability that you don't want to lose. You will lose that on a Fat Boy, they're cruisers with a slower reacting wide glide and fat front tire. The softaiil rear also won't be as kind in the twisties. There's a reason some folks refer to them as sloptails.
BTW, I just test rode a 15 Low Rider a few weeks ago when looking at new bikes with a friend. I only took the Low Rider to 75mph, but was pretty impressed. If I was to buy a new bike, that would be my choice. It will be an excellent upgrade to the Sportster. I just can't see how anybody could regret making that move.
