Obviously from a technical perspective the Speedmaster Super Racing has a lot to offer as it uses the Spirate system that is so far the only Speedmaster to use it as far as I know and whilst still a Speedmaster it does have some other interesting design features as well. There are so many Speedmaster Dark Side of the Moon watches it really would help to know which model you are considering. But really at the end of it all there really is no wrong or right choice only which one appeals the most to you that counts.
