Which telescope should my Astronomy research paper be on? Compton or Hubble?

I have these two choices. The paper must be 10-15 pages and needs to describe the mission, workings, history, how it changed astronomy, etc. He'd probably want me to do Compton because it's more obscure, but I can't find that much information on it online. Which telescope should I pick? Would it be too hard to write a research paper about Compton?
