It depends on the circumstances.   There should not be a "one-size-fits-all" approach.  Ever.   Use the right tool for the particular job you are doing.

For example, if you're doing an output-only list that could potentially show thousands upon thousands of items, then that'd be an obvious use for page-at-a-time, but you should also be thinking of the fact that the user is likely never going to page through that many items, so maybe it'd be better to offer more filtering.

On the other hand, there are distinct advantages to load-all type subfiles.   For example, you can have a proper scrollbar to use in scrolling through them -- which isn't possible with page-at-a-time, because it doesn't know the total size of the subfile, and therefore can't do a proper scrollbar.   As you start moving to GUI tools instead of 5250 green-screen tools, this becomes more important.

Even if you stick with green-screen only, 1980's style, applications there are many cases where load-all subfiles work better.   They are easier to write the code for, for example. For entry subfiles (for example, the user is entering an invoice) they are much, much easier to deal with because you can have everything stored in the screen.   And there are many applications where you know up-front that you'll never need more than a few hundred rows, so there's no advantage to using a page-at-a-time.
