Help: flavor is better with other tanks?

I have the SMOK big baby beast and baby beast tanks with the tfv8 Baby q2 coils. The other day I went to a shop and taste tested an awesome dunkaroo type juice. Loved it on their sample tank, and when I got home, I filled one of mine. It tasted just ok in my tank, nothing special and not nearly as good as at the store.

So I’m starting to think that these coils suck (half burn out so quick anyway), and don’t give the best flavor. Am I crazy? Anyone else experience this?

If I replace my tanks or coils, what should I try? I’m working with the AL85 and don’t need to go too high wattage.
