We had an XO-1 side by side with a non-XO Campfire back in November, along with Dave Perkins to explain what he was shooting for. Unfortunately this was a couple hours into tasting some other lovely pours, so no detailed notes (tanssaafl - not sure if you recollect any specifics?). I do recall there being a subtle difference between the two, but not overwhelming so (which was their goal). I liked both; don't recall preferring one over the other. Don't have a standard Campfire on-hand, but will bring the XO to the next GBS event to repeat the comparison.
