From what I've experienced, the Unflavored DIY WTA really is flavorless now. I enjoyed the subtle flavor of the old stuff, but it did not mix well with some juices. The new stuff however, mixes with anything.
The WTA "effect" is much stronger now as well. The old stuff I could vape straight with no other effect than a general sense of wellbeing. The new stuff induced what is referred to in some circles as "couch lock." I was somewhat unproductive that day. Lesson learned, I mixed the remainder of the DIY with Beatle Juice.
Edit: I really have not been tempted to buy any of the 2 competitor's products.
I haven't read any comments from Dvap regarding the Milk vendor, but the appearance of the product was enough to dissuade me from even trying it for comparison. The liquid looks more like a NET than what I've come to associate with WTA.
I've heard enough comments about the taste of the product from people about the other vendor to also not want to give that one a try either. My understanding is that the chemical taste is in every bottle...but some people can't taste it for one reason or another.
While Jerry might regret not holding a monopoly on commercial WTA anymore, he certainly can be proud of the fact that his WTA is still the best WTA available in the world! (in my opinion).
