Buffy is my all-time favorite show. But I've seen most of the first two seasons of Farscape and some of season 3 on TV and it seemed like a great show, too, but I might not be able to give a proper judgment until I watch the entire show from start to finish (it's been on my watch list for a while). I'd say, watch both, in whichever order you want, you can't go wrong with either. The two shows have similarities: they are both really original, quirky, with great characters, they mix drama and comedic moments successfully, they contain pop references (especially Buffy, but Farscape has its share, too,thanks to the main character), they subvert stereotypes, particularly gender stereotypes; and they both suffer from the fact that many people don't take them seriously before they start really watching them - Buffy because of the name and subject matter, Farscape because it uses puppets for alien characters. Like others have said, Buffy takes time to find its footing. There are some really cheesy episodes in season 1, and production values and some of the acting weren't that great, either. But season 1 is still worth watching (don't skip episodes, even when they seem standalone, the character development is important), it gets better (the last 3 episodes are really good, especially the finale) and the show takes a huge leap in quality in season 2, especially the second half of season 2.
