Neither of the species you mentioned is particularly hard to breed given the right conditions (and a compatible pair), so the right one to breed would be whichever species is rarer there - my guess would be sun conures.
But like everyone has said, breeding is a serious undertaking. Pairs and babies require a lot of care and you will want to have a vet available to go to for problems. Even if everything goes perfectly and the parents take good care of the babies until they wean, there's still a lot of work involved - fresh veggies and other foods 2-3x a day (at least while they are feeding babies), lots of handling and socializing of the babies so they end up tame. If there are any problems you might end up with babies needing to be handfed every few hours, or worse, sick or stunted babies.
Also, I suspect these birds are less common in the Philippines but in some areas, there is a problem of unwanted birds that end up in shelters. Sun conures, while wonderful birds, can be very loud and some may lose their homes due to the noise they make bothering people. Being a responsible breeder also means educating potential buyers and warning them of potential drawbacks to help ensure and babies you sell do end up in forever homes.
