I recently faced the same choice between Ardbog & Uigeadail, without having tasted either. I went with Uigeadail because I love other sherried Islays, but I was very disappointed. Maybe it was a one-off problem but the bottle I bought had a pronounced sulfrous quality, like maybe the sherry cask had gone bad. I later read that earlier bottlings are better, and I regret my decision. I should have gone with the 'Bog or the Corry.
