Yeah, I know... there've been other Firefly threads started recently, but they've mainly asked which episodes to watch or what the whole fuss was in the first place. Instead, I'll give my suggestion to the question asked in the title of this thread, and you're all welcome to agree, disagree and/or add to it (this is assuming that you can afford to either buy or rent, or can borrow, the DVD set). 
Personally, I would do both. Or rather, I would record each episode from the Sci-Fi Channel (particularly if you have a DVR) so as to encourage the channel to show more of the show, but I would actually watch the DVD's instead for the following reasons:
1) Convenience: You can watch the episodes at your pace. Though you can also do that once the episodes are recorded onto your DVR, that takes up the DVR's finite storage space.
2) Widescreen: The episodes on DVD are shown in widescreen/letterbox format. The episodes on the Sci-Fi Channel are not.
3) Clarity: Depending on whether your city's cable system had placed the Sci-Fi Channel on an analog or a digital cable channel, the clarity of the episodes aren't quite crisp. They certainly are crisp on the DVD's.
4) Extra DVD goodies: Commentaries, documentaries, etc. This is pretty standard for DVD's nowadays.
Are there any other points I've missed one way or the other?
