Is there a quick comparison list of the different Warhammer 40k Space Marines Chapters?
Space Marines are part way through a redux at the moment so a few chapters are still waiting for new books (Imperial Fists and Salamanders) which should launch shortly. 

The tactics pages on 1d4chan can be useful but they are not family friendly! The go into a lot of detail but the pros/cons section can give a good overview. The space marines page covers most loyal chapters and then the Dark Angels, Blood Angels, Space Wolves, Grey Knights and Deathwatch get their own pages.
