For my new web app, I'm debating on using multiple views, or conditionals within views.

An example scenario would be showing different info to users who are authenticated vs non-authenticated. This could be handled a couple ways.

1. In the controller, check IsAuthenticated and return a view based on that
2. In the view, check IsAuthenticated and show blocks of info based on that

Pros of multiple views: Smaller, less complicated view - next to no logic in the view

Pros of single views: less view files to maintain

The obvious cons are the opposites of the pros: more files to maintain or more complicated view files.

Which do you prefer? Why? Any pros/cons I haven't outlined here?

Update: Assume each view uses a layout page and partial views to abstract the obviously repetitive code.
