Dogfish just doesn't make any beers that are that outstanding to me. I'll give them credit for Palo, WWS, 60 and 90 min., but nothing else stands out to me. They do push the limits with beer though, which is good I guess, but their one off beers have never done it for me.
Sierra Nevada is a great brewery, putting out very good, affordable everyday beers. I buy a ton of beer from Sierra Nevada, they know what they're doing. However, again, nothing over the top must have beers for me. I think if they start to put some Imperial Stouts and Barleywines in bourbon casks, then you'll see some of their stuff break into top 100. (they are doing Bigfoot in bourbon barrels soon I think, I'd love to get some
)
Beer is like cigars, wine, ect. It's a very subjective thing.
