Orange, even if it's artificial flavor it tastes so fruity, I've loved it for years. When I was younger I didn't really like the taste of mint but recently I tried it again and was surprised I sort of enjoyed the mint-a-listic flavor. But orange is by far my favorite tic tac and nothing can replace it. Go tic tac!
I love the Orange flavor the most; I haven't gotten any recently as the flavor wears off within a few seconds and I am far too impatient to let it melt away in my mouth. Alas, I get Starburst or Skittles as a substitute.
