Which do you prefer, Nikon or Canon?

Nikon, but primarily depends on what you're photographing.

If taking photos of people, then what, and what if sights?

I have an unfair bias towards Nikon simply because I have more experience with them. Either one is good quality. With those scenarios, both could be excellent, so I would weigh the cost of the camera as the main factor in determining what to get. Don't just take my advice though, as there's probably people here who could give better advice.
