All of the reviews I've read say they are great with people, other lion headed bunnies and some other pets (depending on that particular pet's temperment). They love attention and have their own personalities.
Back to reality though. I don't know too much about rabbits. I never had one before and don't have any supplies that they need already. I know that part of the care of rabbits is that they require lots of fur grooming. The Lion Head Rabbit doesn't shed as much as other rabbits when they are older. BUT when they are younger they go through stages of shedding. The mane on it's head is made of wool so really have to comb it out or else they could injest too much of their own fur.
Here's what the lion head looks like:
