I received the "peace + tranquility" candle as a gift for Christmas. I loved the smell so I wanted to try others. "Joy + laughter" smells amazing. I will say "peace + tranquility" has a more clean/refreshing smell, while "joy + laughter" is more sweet- almost like a perfume. I plan to try more scents in the future because I love these so much! Definitely would recommend. PS. I am sensitive to strong scents (sometimes get headaches from them) and these do not bother me.
