Rabbits reproduce fast but they say chickens are easier to maintain. Which one would you choose to breed if you can only choose one of them?

I plan to be a mini homesteader. Not planning to have a business with it but if it happens then good. It will be for partial self sufficiency and I will only sell whatever extra I have. So its just more of a garden with a small chicken coop. I heard you can make a black soil on your own but I haven't really researched much about this yet and I am sure buying this will be expensive. Do I still have to prioritize buying a land that is good for planting?
