I think it's hard to generalize as it's dependent on the application
and the specific action how much work the controller has to do up
front.

I might have a page that displays a user and their related
information, and all I might put in the stash is the user object.
Then in the templates:

    <div id="content">
    [%
        PROCESS personal_info;
        PROCESS tasks IF user.has_tasks;
        PROCESS alerts IF user.has_alerts;
        PROCESS calendar;
    %]
    </div>

Or something like that.  Seems natural and allows the template
designers to decide what elements to include and the structure of the
resulting page.

No clue how that works in Seamstress.
