My favorite career is Scientist. I don't like social work tasks like gossiping or chatting with co-workers but I do like having access to collectibles and being able to use the equipment at the lab. I also like having my Sims visit planet Sixam. All of the Aliens generated by this career are later humanized with MCC because I don't want to see 17 adult and young adult Aliens at every social event. On the other hand, I wouldn't mind seeing 17 new Vampires in my game. Unfortunately, my game only generates one or two Vampires that are always elder females with no skills. They get deleted.
I also like the Freelance Programmer career.
