I was a Woodwick customer before Yankee. The crackling of the wooden wick, the full aroma scent from the burn, and the fact that the candle burns ALL THE WAY DOWN (no wasted wax) are the key features for me. I am currently pairing Fireside Elipse with Yankee's Crisp Fall Night (HEAVEN).  Then at my office I have Pumpkin Butter and Cinnamon Chai pairing together! The crackling wick and the aroma of the pairs keeps my sanity level at work serene.
