Just wanted to share my thoughts on this brew mainly from a flavor perspective (mainly because I don't have a firm understanding of categorized beer styles).
First off let me sing some praise for the Burton ale yeast. When I first tasted the starter I made I nearly dumped it because I thought it could be infected, but a quick Google search showed that this is high acetaldehyde yeast. It has a massive fruit taste that just totally completes this beer.
The second thing you notice with this beer is a high degree of roast. This combines with the high fruit from the yeast and just absolutely wows you with flavor. It's not dominant in chocolate or roasted barley or even the ton of brown malt, just a perfect combination of the three that also blends perfectly with the yeast. The alcohol also seems to blend in at a perfect level as well.
I can't comment on the hop level because I can't pick them out of beers other than massive IIPA style, but they certainly don't detract from the recipe at all.
This is actually one of the rare brews where I don't have any comments on what I would change for the next time brewing. The closest thing I could use to describe the overall flavor would be "a spot on clone for Guiness Foreign Extra Stout".
