Alot depends on which parks you will be going to. Cypress Pointe is very close to Disney while HGVC is very close to Sea World and closer to Universal. Both are obviously not far from any of the parks.
Depending also on the unit size, they both offer up to 3 bedrooms and if it were deciding between a bigger unit I would take the bigger unit.
HGVC is overall a prettier resort and newer. Cypress Pointe Grand Villas is a smaller resort with nice pools.
I hope this helps some.
