Moderates have more features and amentites then values. With that being said I would stay at CSR imo. The food court and grounds are better, and they also have things that some deluxes don't have since it has a convention center.
If you can get Coronado for $114 more for the entire week it is TOTALLY worth it. Pop is great, but CS has much more of a resort feel-especially if you are traveling without children-they will be at both, but will be running around much more so at POP.
We have stayed at both resorts in the last year and I would definitely go with CSR for that little of a price difference. You won't be sorry! Just the nice mattresses and having the fridge is worth $114. The transportation is the best at CSR too.
Although we do LOVE Pop, for only $114 more, we'd definitely stay at CSR!!! Our summer trip was at Pop, and our upcoming trip, we're trying CSR again!! DD can't wait to try out the slide!!!!!!
