Celebration Bottle Recommendations

Looking for recommendations on a celebration bottle in the $300-450 price range. I’m a big Dalmore fan and my favorite bottle ever is the King Alexander III but would like to get something different. Big Highlands and Speyside fan, don’t care for Islay. Looking for recommendations!

Have thought about Glenmoragnie Signet or Dalmore 18… what’s your pick in this price range?
