In fact, I did comare Yamazaki whisky to Islay whisky using this (http://rsearch.ca/static/compare) web interface I made specifically for cases when people claimed that any two things were "not comparable".

The results for Yamazaki include: smooth mizunara hakushu hibiki

While the results for Islay include: peat smoke barley caol

Actually, you seem to have provided a comparison yourself: one is heavily peaky and smoky, and one is not. Seems like a pretty good comparison to me.
