I disagree with this assessment.
For instance, I DIY a particular LorAnn natural Pear flavor (one of the very few natural flavors they manufacture) to a ratio of 1 drop per 12mls using a ceramic wicked AGA-T2. Both my Atmizoo Roller and dirt-cheap Lavefire mechanical mods render a sweet smooth taste, very lovely. All the electronic mods, be it the Provari, eVic or ZMAX completely .......ize the taste to the point of being nearly flavorless, both the Provari & ZMAX adding a rather harsh edge to it.
I suspect it has something to do with the power-cycles of these electronic devices, whereas the mechanicals don't have these. It's for this reason I don't use my electronic mods very much at all.
I have thought about the power cycles before when considering mechs, and concluded that it should not make sense: 33.3 cycles per second on a VAMO and flat line DC on a mech should not be detectable by human sense of taste. The temperature of the coil should not oscillate nearly enough with 33 cycles per second.
Then i came up with another explanation: the calculation for wattage is skewered. For example, i vape my AGA-T2 on a VAMO at full power 15W (arguments can be made whether or not it actually reaches 15W unstacked, but it is full power). On a 0.9 ohm coil, a mech that puts out 3.7V should put the coil at 15W as well. However, due to voltage drop, inevitable in mechs, you are actually running much lower wattage than the math would yield.
The most accurate way to determine the numbers, in my opinion, is to meter between center post and negative screw of the RBA: at 15W on VAMO, 1.2 coil, it reads 3.8V. On my mech, same coil, it reads around 3.2V. I meter on the VAMO again, adjusting wattage with each try, and 3.2 between post and screw corresponds to 11W on the VAMO.
Try that and let me know how it goes.
