Yes, usually their genetics are stronger from being from the wild or closely related to it and theres not as much inbreeding going on but as long as you get your fish from a reputable source you'll never have this problem. I like f0's because I know they are pure breds, they usually have nicer colors, and they're just a lot cooler knowing they're wild caught but at the same time they're not as hardy in the aquarium. For instance.. I can get line bred discus and bring them home and put them in my pH of 8. If I got one from the wild I would never be able to acclimate it in to my water. There are good qualities for both, it all depends on the type of fish you're getting whether or not you should go with wild caught. Morale of the story is to know where you're getting your fish and to know who you're getting them from.
Great points there, also for me, the main reason I would get an f0 would be to make sure it a pure fish, especially if it is a Vieja or some other kind of cichlid that is really watered down in terms of hybrids. Then I would get an f0 or f1 from someone like Rapps.
