I'm reading the FAQ at the Blu website and Eonsmoke website and they say that the vapors are made of different chemicals... Blu apparently uses vegetable glycerin and Eonsmoke uses Propylene Glycol (perhaps the cause of that weird petrol aftertaste?). Of the two, I find I prefer the VG in the Blu disposables, so far at least.
I don't appear to have any allergies to the PG, so what's the real difference? What are the pros and cons of each base fluid? What does everyone here prefer? Do they made any difference in flavor or vapor quality?
