What's your opinion on rats, why?

Hey what is your opinion on rats. And Why? Ive had 3 and I recently got my 4th. I had a white albino named Dolly. Another white albino named Peppermint. And a black n white hooded rat named Bean. My new one is the first male ive ever gotten- he is a white albino named Jimi. I love rats, but what do you think of them? Haha! Plz n Thanks! :D
