Gosh....tough to be specific and only pick three.
Chocolate with caramel... preferably dark chocolate
Chocolate with peanut butter... preferably dark chocolate
Chocolate with almonds... preferably dark chocolate
Expensive fancy chocolate to Hershey, Mars, Russell Stover and Cadbury....I like it all. Except, not a fan of cheap dollar store like (no brand) chocolate that tastes blech.
Fruity type candy...I like Red Swedish Fish most. My DH and three kids prefer fruity candy to chocolate which is blasphemy to me. I will nibble on the gummy/fruity stuff but don't crave it or binge on it or seek it out.
This time of year I have a hankering for candy corn.
If I had a kid who went trick or treating and came home and dumped his candy on the table for me to pick three pieces....I would pick a dark chocolate milky way, a Reese's peanut butter cup and red swedish fish.
