Is it better CPU performance-wise to write one big script in the onLoop, using a task based system, or using states?

no real difference, it's just a framework for the code that you're already going to write.

Whatever you prefer, but personally you should use task based system.

Every less if statement you use you shave off nanoseconds of CPU usage needed to evaluate the expression

And countless more errors you introduce

depends really, if done well i dont see a massive issue. 

What tends to happen with task based scripts is there is alot of repeated code in each of the task 'validation' methods that could be avoided if it wasn't and this can cause usage to go up.
