I don't find any categorical difference in vaping tastiness and authenticity among the three standard divisions of pipe blends---Aromatic, Non-Aromatic, and English. I've had good luck and not-so-good luck with extractions from each genre. For example, my extractions of Cornell & Diehl Autumn Evening and Hearth & Home Burley Kake are wonderful Aromatics to my palate.
What I do notice, whether with pipe blends, cigars, or cigarette/RYO tobaccos, is that vaping tobacco extracts is a fundamentally different experience than smoking tobacco. The flavors may be in the same ballpark, but the sensations that surround the flavors and contribute to the overall experience are completely separate. Each method provides elements that the other lacks. This is the case with all three types, but is most obvious with cigars. Smoking cigars is a very direct, high-impact experience, almost blunt in its intensity, while vaping cigar extracts gives a more abstracted experience, emphasizing refinement and nuance. Smoking cigars strikes me as more satisfying than vaping them. I feel the opposite about pipe blends and cig/RYO tobaccos, however---vaping those provides a better overall experience for me than smoking ever did.
