I think this does come down to how you use a bike. The Hunqapillar and the Bombadill are both really designed for rough, single track riding. And for that application the 2TT solution probably has a slight advantage. If you will be primarily riding on roads, even dirt roads the Atlantis or AHH should be the bike of choice. Personally I have no desire for a mountain bike and don't much care for the looks of bikes with TTs that slope more than 2%. I suppose if you are mostly an urban rider or have a strong preference for mustache bars and never stand up on the bike, or have a back that no longer bends, then the 6% lift can be a good solution, and the 2TT may also make sense.
My tandem has a sharply up sloped TT, which accommodates the smaller stoker compartment and I think that looks fine. And, of course it has a middle tube which runs all the way to the stokers seat. But fully loaded for B&B touring it weighs about 425 lbs! It doesn't flex; it doesn't sway; it doesn't ghost shift. For road riding I cant believe a 54 cm bike, even carrying about 225 lbs. needs that kind of reinforcement. I live in a town with almost no paved roads, so much of my riding is on dirt roads. I'm 6'1" tall and weigh (unfortunately) 192 lbs, but I find, depending on the road conditions, either 32 or 38 m tires are optimal for riding on dirt roads. Some might prefer a bigger tire but I don't think anyone needs a 50 + mm tire for road riding, which is the big advantage of the Bombidill and Hunqapillar.
