You don't need to use collections if you don't want to save the values before they submit the page , for example, reloading the page after changes,adding multiple rows etc. You can also use your package to handle DML's with this approach(infact you cannot do it easily with builtin tabular forms) , here's a discussion on that : {message:id=9437137}.
As for the question of performance, a comparison between using a direct SQL query and collections approach has been done here : {message:id=9413326}.
But the collections method should compare to the builtin tabular form in performance, since it practically has to do the same steps(internally) and additionally always does a checksum comparison.
In any case, how many records are we talking about updating a the same time, you do know that any of these approaches _process only those records in the pagination page(ie the first 15 records fetches by default) and not on the whole result set_ ?
I would suggest you to get familiar with using this approach first before worrying too much about performance.
