LOL- No one scent is ever better or worse. I have all of the scents you list, except for the Yum, and some you don't list, and quite frankly, it depends on the day.
For example, I was fishing two years ago without scent and was experiencing nothing but follows. I placed a glow worm scent from Mikes Baits on it and caught a fish on every cast for the next 30 minutes. The Berkley nightcrawler did nothing for my friend.
Most of the time the glow worm is of little use, and more often then not the Berkley is better in the worm scents.
You have to let the fish tell you what they want. All I can tell you is that this scent works well, more often then not, and it comes in "flavors" I need.
