I've got the TV Vanilla Cheesecake and a vanilla-cupcake-something else mix as well. And I totally agree- they're carto murderers. One day tops then they taste of asstastic sweatsock, lightly scorched. I find them pretty good dripped on a regular 510 atty, not awesome like the first half day in a carto, but definitely you get flavor. However, on my LR 510 atty? Not a bit of flavor to be found. It's not just you! They're really frustrating- get em hot at all, too, and you get utter nasty even quicker.
Honestly? I had to DIY anyway because I can't vape PG (which put my favorite, the TV cheesecake, right out) and I haven't had that same problem with DIY cheesecake flavors, even though The Perfume Apprentice's cheesecake tastes like what TV uses. So I don't miss it much. If you're up for a little challenge, try to dupe it DIY style- it's a bit of $ up front but much cheaper in the long run, and I've personally loved most of the flavors I've tried since I stuck with some good flavor vendors (NOT Lorann's!) and mostly bakery/vanilla/fruit flavorings that play well together in general.
I just looked and Flavor West makes a Vanilla Cupcake- maybe try that, plus a little of The Perfume Apprentice's Bavarian Cream and maybe some Capella's Vanilla Custard. That'd be my best guess...
Otherwise, I'd say since you discovered dripping on a 510 atty works OK, to go with that if you're happy enough- personally I wasn't thrilled with the TV juice in it- I got some flavor but it was still a little muted- but it was better than going through dozens of cartos.
