Cypress units are bigger and resort is really nice. Spa and work out facility is very upscale for a time share. No restaurant on site other than the typical Marriott stuff. Around the corner from Sea World.
Sabal. Older, not really a resort, but it is on the grounds of the World Center that is a big resort complex. No real feel for anything that defines itself, but units are great and proximity to Downtown Disney is about 10 minutes closer than Cypress.
I would go look at reviews, pictures, etc. and make a decision.
Bottom line is that you will be happy with both.
