Difference between different key types

[Jerry]

This is probably a stupid question; however, since I am relatively new
to gpg, I was wondering if someone could briefly explain this to me.
When creating a key, I am presented with a menu offering four
possibilities:

   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)

What is the difference between choices 1 & 2? Is one better than the
other? Which would be preferred? I am assuming #1; however, "KGPG" (In
the KDE suite) seems to prefer choice #2.
