Pretty much every breed of rabbit is very lovable and affectionate towards their owners but the top 4 rabbits that are very affectionate rabbits are the Rex Rabbit, Lionhead Rabbit, Polish Rabbit and the Netherland Dwarf Rabbit.
I personally had a Rex Rabbit and it was very lovable to me and my family when I was a kid and would have one again if possible but I can't have one in the rented house I'm living in right now.
