Weakest and strongest syrup flavors?

Hi all!! Trying to cut down on my caloric intake, and it got me thinking about which starbucks syrups give you the most bang for your buck, so to speak.

I noticed this year’s pumpkin spice is pretty weak, even with 3 pumps in a tall I can barely taste it. Same with brown sugar. On the other hand, even one pump of hazelnut comes through for me pretty well in a grande.

Which flavors do you think are hardest to taste in drinks?
