As noted by all the others its a matter of preference. If you like the look of the retro spoke wheels and lotsa chrome go with the America.
If you like the rims and the lack of chrome and the deadly black look of the engine block go for the Speedmaster.
Ideally I feel the all BLACK shiny speedmaster is the best way to go. The all BLACK speedmasters have been scientifically proven to be faster that the others and look flat nasty with a good wax job on the paint job.
Undeniably the Black ones are the fastest most wicked ones on the road.
It is written in revelations that Jesus rode a Black speedmaster.
Thats good enough for me.
