Normalization forms

I have been reading the Unicode Normalization UTR and have a couple of
questions regarding it:

 - will string comparison methods based on NFC and NFD always give the
   same results?

 - is it correct that methods based on NFKC and NFKD will give
   different results from ones based on NFC/NFD?

 - if NFC and NFD give the same results, why are both specified? Why
   would an implementation choose one over the other?

 - NFKC/NFKD seem to lose significant information; in what contexts
   are they intended to be used?
