I have been meaning to to a side by side with the two yeasts, I think it would be a good experiment.
Despite my slagging it is clearly possible to make great beer with US-05. I tried Dunfie's Punk IPA clone with US-05 and it was great. There is no doubt in my mind though that when I make beer with US-05 it doesn't turn out as good as when I use WLP001. It could be for any number of reasons. I would love just to be able to throw a pack of yeast in the wort. Also I think Nottingham makes a cleaner, better tasting beer than US-05.
One last thing, the cost argument is a little less compelling now that Fermentis have put the kibosh on repackaging dried yeast... :x
