I guess SSR is classed as a deluxe because 1) it is a DVC property and 2) unlike the moderate resorts the rooms do have a private balcony.
The pool at SSR is nice (haven't used it, just saw it as I used the SSR spa), the only thing I do not like about SSR is the reduced facilities there (options of Disney restaurants etc), but I guess you are so close to DTD you could use facilities there. Also, for me, the resort is too spread out.
