I've never had the Oogie other than a single sample. It is quite nice, but I can't give a fair/proper comparison between the two. I do have a full (well...now half full) bottle of Laga 16. It was the dram that got me hooked on Islays at a tasting just over a year ago. A truly awesome bottle that I find shows something different almost everytime I have tried it (orange, pine, and various herbal notes on various occasions, for example). I have also tried a Dun Bheagan Islay 2002 that I have been told is an 8-year old Lagavulin. With Laga 16, there is an additional sweet element to it that adds an extra dimension.
If, like me, you're budget conscious, try to find Laga 16 in the 200 ml mini bottle (or as one of the taster packs, like the strong collection, which includes the Talisker 10 and Cragganmore 12...if you would like to expand your research/discovery further!) if it's available in your area. Whichever bottle you choose, you can't go wrong.
If you get the Laga 16, you can then impress your non-whisky friends with the fact that you have a 16 year old bottle of whisky!
The wishlist is always growing...
