SawII vs Original. which is better?

[lumpisan]

Im a huge fan of the two Saw movies, haveing seen both in theatres. Now, I liked both, but I can not decide which one is better. The frst one had a good plot and was basically a hugeass mind-f***, but the deaths kinda sucked. The second one had a decent plot, but better, more elaborrate deaths. So, I take it to you, fellow Mockers. Which is better, Saw or SawII? Style, or substance?
