I disagree. I believe it is down to each individual as to how sensitive all their "taste" cells are and where they are. It's not just tongue, it's nose, throat, sometimes lips and the combination of these with the quality of the carrier nerves that take all the information to your brain which is where the taste is decided on.
Depending on your health (stuffed nose? you won't taste much etc) and your sensitivity to smell/taste, you may need to savour the vape more in your mouth in small dense amounts or you may prefer to utilise larger amounts of vapour and simultaneously experience the various flavours as the vapour travels in and around you.
Unless you're vaping a single flavour juice, it's difficult to compare set ups. I prefer good blended juice with lots of different flavours and aromas so different set ups and vaping techniques will emphasise different aspects of the blend.
A few recent sensible explanations on here about why people enjoy mechs makes absolute sense to me (but I have no interest in using one). As the voltage varies the vape changes so you may get to taste many different aspects.
Or just train your senses and use any half decent set up and vary the power of the vape to suit the juice and what aspect of the juice you prefer.
Taste is just an accumulation of comparisons built up over your lifetime.
So whatever you find that gives you your "best" taste experience is the one that's "best" for you.
