If I am doing a really complex assembly (350-400 components), which approach of the two should I utilize - top-down or bottom-up ? Will really appreciate if you support your answer with little reasoning. Thanks !

Inner components out, less turning on and off visibility of certain components. But from the bottom up would be my suggestion I guess, it makes it easier starting point if the bottom is centered at the origin for making exploded views and rendering usually. It depends on the assembly.

You can have a mixture of both. You can create the top level structure using top-down methodology and use the bottom-up approach to work on lower level assemblies. For an assembly this size, I would use a top-down structure.
