Both are good choices IMO

What kind of trip are you doing? If doing a couple of resort days, I'd be inclined to do the tower for the week (it's awesome! and we love Coronado - we stayed there a couple of times over the last year for virtual school and work). But if spending pretty much every day in the parks, I'd do the split since I'd just want a place to sleep on those days. We've not done theme park view, but it sounds like a great way to end a trip!
We have a 4-night stay next month and are doing a 2-night All-Star Movies/2 night Contemporary (Garden room) split. But we are only doing one full park day (the day we're at Movies) and a Boo Bash after we move to Contemporary - so we'll have a lot of time to explore monorail resorts and just chill at the Contemporary and hopefully catch some fireworks on our down day. Originally, we booked 4 nights at Music but didn't like the idea of not a lot to do there on our down days and limited food options.
