I've got a system that has the best of both. The BEST Ditto breeders you could ask for. Everything's top-notch on them (yes, they're genned). I go in and breed up Kalosian Pokemon with them. After about 30 minutes, I have the Pokemon I want, after an hour, I've horde trained it, after 3 hours, I'd Battle-Chateau-farmed to death with it and it's level 100, ready to rek.
