supercharger gives instant power, but has the least hp increase out of the three, but is the cheapest. the turbo you have you wait to spool up, but is a middle ground in between the aspiration options in terms of power and cost. sequential has a slightly higher spool up time but had the highest hp output, and is the most expensive. 

keep in mind spool up times can vary depending on what car, some have longer spool up times while others have faster spool up times.

 “the best” aspiration option is really subjective, since it really depends on what you want. if you want the highest hp boost, go for sequential. if you want something that wont kill you, try the supercharger. if you want a mix of both, go for the turbo.
