TextMate? I don't use it myself (it's not free) and I'm not sure about the "ultra fast" startup time, but I believe that it can work with RTF. http://macromates.com/

Stickies is the best RTF editor I've found. I wish there was something a little more powerful that will handle multiple open documents a little better.
