I'm firmly in the don't know category as I haven't used stock coils for over 5 years.
Wherever possible I don't buy kits and prefer to wait until mods are available for sale - the last new kit I bought was a Vaporesso Gen X kit that was being sold cheap. However, this was basically a 4 year old mod and the tank that came with it was even older and used Smok Baby Beast sized coils. Although I've found Vaporesso coils to be better than Smok equivalents, even though one coil was mesh, it was still a 5 year old coil design and probably not a good representation of the current generation coils - as it was a 2ml TPD tank I didn't bother vaping on it and threw the tank and coils in a tupperware box with my other old stock coilers for the sad day when my hands are too shaky to build.
Although I found mesh stock coils to give far better flavour than the oldie worldie round wire jobs from circa '17 I wasn't quite so impressed by the cooler vape and found rebuildables better, not specifically for the flavour, although they were definitely better - but mainly for the warmer vape from complex wires in DL rebuildables. When I did vape DL mesh stock coils I found myself pushing the wattage because of the cooler vape which resulted in early coil demise - and of course they absolutely swilled juice.
To be quite blunt I've never liked the cooler vape of any mesh, stock coil or rebuildable - except when the temperature is above 30C outdoors, which tends to be for about a week or two every other year. In these short spells I dig out my Nest RDA and enjoy a flavoursome cool vape - but for the rest of the year it stays on the shelf where it belongs.
I'm sure they will have improved over the last 5 years - but I still suspect they'll provide a cold vape and swill juice so I'll continue to avoid them until I have no other choice.
