Having been utterly seduced with great delight by Vapelicious' StL Gooey Butter Cake, I wanted to see how Kick Bass Vapor's version---called Gooey Better Cake---might fare by comparison. So, I ordered some, which came in the mail today.
First I atty-dripped it (using a Joye 1.5 ohm LR atty run at 4 volts), then I loaded it up into a cartomizer (a 1.7 ohm XL SLB Resurrector, my current fave carto, along with dual coils), and vaped it head-to-head with StL GBC, which I keep loaded and topped off in a 1.5 ohm mega XL dual coil. I used two Madvapes VV boxes for power, set to 4.1 volts. (Those particular mods concentrate flavors better and hit harder than any other PVs I own.)
As we know, KBV is very good at sweet dessert vapes, and their Gooey Better Cake has that signature KBV sweet taste. The overall profile is flavorful as well, with a quite obvious cakiness that has lovely depth. BUT (and I say this without meaning any offense to the good folks at KBV), their version of this regional delicacy cannot hold a candle to Vapelicious StL GBC, in my opinion.
Candy's juice excels in two elements---it's extremely rich, and---just like the name says---over-the-top gooey and buttery. In all honesty, I wouldn't use either term to describe KBV's, which comes off to me as rich, sweet cake.
Now, I was born and raised in St. Louis, and I actually ate gooey butter cake as a kid back in the 1950s. But that was more than half a century ago, and though I recall clearly what the dessert looked like and how different it was from "regular" cake, time has dimmed my taste memory sufficiently that I couldn't begin to judge which of the two juices is closer to accurately replicating the flavor of the real thing. All I know for sure is that the KBV version is a good, flavorful juice, while Candy's version is a truly phenomenal juice, one that makes your brain sit up, take notice, and say, "Wow, I've never vaped anything like this before!"
Just my two cents. Your mileage may vary.
