I've never once even looked at a 4e adventure so I have little idea (Oh wait, I bought ToH for posterity) of what tripe or what gold lies within. However, I have seen Quickleaf's Dragon Mountain and I know the original material quite well. So I'm going to cast my vote with him!
Haha, thanks Manbearcat!
Since this *is* ENWorld and Ryan worked/is working his tail off with it, I would be remiss if I did not mention Zeitgeist as an excellent adventure path available to ENWorlders. It was designed with 4e in mind, unlike War of the Burning Sky (also excellent, albeit the conversion was a bit awkward).
And then there is everything put out by Fourthcore, like Revenge of the Iron Lich, which are excellent albeit deadly old school dungeons.
I've heard some good things about WotC's Slaying Stone and maybe one or two other low level printed adventures, but nothing besides that seems worthwhile. By and large WotC's printed adventures suck IMHFO.
That said I agree with [MENTION=22260]TerraDave[/MENTION] that there are some diamonds in the rough of DDi, the G-Series (converted by Chris Perkins), and the Baba Yaga conversion all look good. Some of the adventures by Raven Kolja-Liquette (sp?) are also quite good. Then again, there is lots of suck to sort thru.
EDIT: Oh, and the Living Forgotten Realms/Organized Play adventures may be good also, from what I've heard, though I have no experience with them. And they're all free to download...which is nice (Bill Murry voice from Caddyschack).
