Modular Factory or One Mega Base?

Good morning, Engineers,

I’m getting back into the game after a long time without playing. The last time I played, I reached Stage 3 of the Elevator (right at the beginning).

In this new save, I’m going to try to progress further, maybe even complete all the stages.

One question I have about designing the factory layout: is it a good idea to build the factory in modules? For example, make one module that produces all the items up to Delivery 1, then start a new factory somewhere else that produces everything up to Delivery 2

Or is it better to build one giant factory with all production concentrated in a single place?
