Feeder rabbits tend to be bigger breeds are do have a different body type. There are a few breeds that are commonly used as meat. Common breeds are the Califorian and New Zealand, but there are others.
As far as other breeds, it really depends on what you may be looking for. Meat breeds tend to be bigger, so if you are looking for a small rabbit these are probably not the best choice.
Any breed can make a good pet. One thing about rabbits bred for meat is that they tend to not be bred with the health of the rabbit in mind as they usually don't live too long. While this usually doesn't make a huge difference since many breeders don't specifically breed for health and longevity. You should try to choose a healthy rabbit.
What you really need to take into account is the size of the rabbit. There are a few meat breeds that have red eyes and they can freak some people out. If the rabbits you are looking for don't have red eyes, they don't develop them later on, if that is a concern for you.
They might have some issues with food since they probably haven't been given hay or veggies. It may take some time to get them eating these and used to eating them. There may be some sensitivities to foods, so keep that in mind when giving new foods.
Breed doesn't make a ton if difference with keeping rabbits as pets. There are some differences, but these are usually related to size, fur (amount of grooming), and energy level. Other differences can be due to the sex (some intact buck will spray and hump and intact females can be moody), and just the individual rabbits.
If you want to get one of the rabbits, then go for it.
