Its both depending on the technique you use, you can issolate the back of biceps more. I do chinups on biceps days."In AUSTRALIA
Each year there are 470 000 adverse events, 18 000 deaths, and 50 000 permanent disabilities arising from medical error and negligence each year. This is four times higher compared to the USA." (Second oppinion, GERMOV quote, page 293)
353 fatal car crashes were recorded on Australian roads in 2008 (RTA, 2008). You are 50 TIMES more likely to die from medical negligence from a DOCTOR compared to being fatally injured in a car crash and they say driving is dangerous.

The only difference in the two is that a chin up puts your biceps into the movement more usually makes it the stronger of the 2 more most people while pull ups use the brachialis muscle to a greater degree and less biceps. That being said they all hit the same muscles in the back and remember the wider the grip the shorter the range of motion as well.
