Drew, I think this is what we are all trying to say - there is no high horse!! You are interpretting these comments as being pretentious, but I don't think they are meant that way in the slightest.
Murry, myself or anybody else saying "I have brewed kits and AG and I prefer the AG" is not a spiteful or elitist comment, its just a comment on what we have found ourselves. Nothing more. I think you are reading into these comments a bit too much.
In my opinion since I have used a similar brewing technique and approach (in terms of sanitation, temp control etc) for both my old extract brews and my current AG brews, I feel this is a good indication of the objective differences in quality. And in my opinion, the AG beers are better. Full stop. If you don't find that to be the case then great, however, I think you need to have some AG experience before objectively making such a statement. That is, in a nutshell, what I think about this whole issue.
