Just a note: the people who keep Automatic Music Spacing selected are usually the ones who complain that every time they add a note, a bunch of other things shift, particularly if they use page view for note entry.
I use page view for note entry all the time; but I do it aware of what automatic spacing can do to it, and I do not try formatting pages until after all notes are in. Then I work through from front to back setting note spacing and page turns and locking systems down.
This is a personal choice of whichever you feel more comfortable with. I usually, 90% of the time, use scroll view. I feel it keeps more of the score on screen than page view does. Afterwards, I check articulations and expressions, page size, margins, etc., and run Perfect Layout. Done and it looks great.
I should say that when I use Page View to enter notes, it is because I am using few enough instruments that page view lets me see multiple systems on my screen. If I were working on a large enough score that only one system appeared per page, I might well use Scroll View instead.
So, as Ernest says, it is ultimately a personal choice; and as he implies, it depends on the circumstances. Use what helps you be most efficient. And best wishes.
