Suntory Hibiki (15 Y.O.), I guess is one well known and widely accepted whisky. Suntory Yamazaki (12 Y.O.) is cheaper single malt (not that Hibiki would be very expensive either), but IMO Yamazaki isn't really amazing.
Steve, if you like peaty whiskies, definitely get a bottle of Yoichi 12 y.o. (not the 10, but the 12). Ardbeg-like peating levels, but still with a character of its own. Among my all-time favourite whiskies.
