The laserdisc had a very nice picture, probably on par with DVD. Not as sharp as the bluray and the colors are a bit more muted. Which could be a good thing, that's mostly personal preference.
I'd probably have to listen to it again to really talk about the audio, but it sounded perfectly fine. I was just using TV speakers though.
Sorry if it's sort of a nonanswer, I don't get to watch the laserdiscs too often since I don't own a player myself. They mostly stay framed.
