most efficient way of loading views

This is just an opinion.
I use something like your controller 1, passing superfluous data to some views which don't actually use it.
I agree that the technique in controller 2 results in faster rendering of pages. As a lazy coder, I don't always take the time to sort my data and pass only as much as needed for each view. Slap on the wrist for me...
Justification: The amount of date being passed is small, usually. The data array is passed by reference, hence the server isn't being beaten on as much as a full data copy would cause.
I look forward to hearing for others on this topic.
