It is warmth, vapor, throat hit, and brings out some flavors cleaner. My flavors all work best at slightly different voltages, depending on what carto I have them in, and this lets me tune without having to think ahead. Haven't gotten around to firing up my normal go-to tob5 30mg yet, since I've really been loving VanTob and just now switched to CarCapp.
I also expect decent runtime between battery changes, since I'm running some fairly high resistance boge cartos, using higher voltage instead of lower resistance to get the desired power. Lower mA draw should directly equate to longer runtime.
