The Carrefour on Bush Rd in Cay Hill is slightly larger.
But both are a good size and carry the same stuff.
If you don't have a car, it is easier to get to the Bush Road location by taking a small public bus, only $2. You would need to take two buses to get to the store in Cole Bay. If you are in Pelican, Market Garden is right beside Burger King at the end of Billy Folly Road. It is much closer but not as big as the Carrefour stores however it has a pretty good selection.
