I'll be honest, I'm very unlikely to read that link - nothing personal, just can't be bothered
I've never tried a smok device, nor a DNA so I'm not (and wasn't) challenging whether one was better or not.
One thing I will say though, with the various chipsets I have I've never thought "this could be more accurate". I honestly don't care if it's outputting the displayed wattage, because I don't really look at it much anyway and I've never measured it (people who say "it feels like a 90W vape" or similar are butt talking imo) - and with TC, I don't care if it's within X degrees of the displayed temperature just so long as it stays close enough to where I set it.
