Firefly had the same witty, tight writing that Buffy did. It's hard for me to compare the two, though, since I hardly got to really know Firefly before it was over. Buffy I can celebrate its wins and mourn its misses. Firefly seems to be 15 hours of awesome and that's an incredible record. Many of my favorite shows (I'm eying you, SG-1) had some real stinkers as they were feeling around in their first season. I would have loved to have at least 6 more seasons of Firefly to see the show in the totality of what it could have been.
