I've said it before, there's nothing wrong with a Harley, but there's something right with a Triumph. We had a Road King in the family for a time and, while it's a lovely road bike, it is just too bulky to fit my style. Between the Dyna and Softail lines, both are nice enough but I like the ST a bit better. You can't really compare them to the America because they are different animals, rather like comparing a 383HP powered Chrysler and a Jensen Interceptor. Same power and gearbox, and close to the same weight but the Chrysler has an 8 Hoffa boot and the Jensen has much better cornering.
