The first question I would ask is if you care about all the Deluxe type amenities that CSR has that POR doesn't?
Fitness center, spa, salon, sauna, lap pool, night club style lounge, also 2 outdoor lounges, 2 table service restaurants, room service, Business Class room option?
If those things appeal to you than the choice is simple, POR is no comparison and CSR is the clear choice.
If you don't care about any of that than it's really a toss up.
CSR:
- Mexican theme
- larger pool
- larger hot tub
- better water slide
- more central location with arguably better bus service.
POR:
- Old South theme
- Boat to Disney Springs
- recently renovated rooms
- POR army that will come by this thread shortly and declare it the greatest place on earth.
