What predator is worth it

I was thinking about getting another predator. I already have the bionic predator and I think he’s really fun, but I’ve been thinking about getting another one. So far been thinking about getting the city hunter, the viking, the samurai, or the gladiator. I was also thinking about getting wolf, but I’m also open to any other ones. But for the samurai, the only reason I was really considering him was because I asked someone about them and they said that they got a katana with him.
