Jase, as I mentioned in the thread earlier I'm not really about speculation and stroking my ego etc etc, so I can only answer based on this kit vs Tony's JSAA recipe followed to a T.
So far, this kit is slightly better at the same age. Tony's extract recipe did come into its own after a few weeks though. I think they are comparable enough that it's not worth differentiating too much. With Tony's recipe I should have strained out the hops and made sure they didn't make their way into the fermenter in my opinion, and with this one I should have been more careful with the pitching temperature.
All in all they're very comparable in taste, very comparable in price, with the difference being that one's slightly less effort and the other is much more open to customisation. So choose based on preference obviously.
I would say these ezybrew kits are about on par with extract brews. They're probably not as good as fresh wort kits, but miles ahead of normal cans of goo. They come out of their container as a full liquid, not a viscus goo, and they come with proper yeast and seem to be made with proper ingrediants etc.
Sorry mate I can only talk from experience and not give you more sensationalist crap to get excited about.
