As others have pointed out the question is a bit of a false dichotomy. I get both by using convection portables like Milaana, Firewood 4, my Fireflys, or even the Supreme with fairly tightly packed little pucks to increase draw resistance (my preference). Then when flavor fades a bit I dump the puck (after removing it and turning it around to work the other side)into my ABV jar. There is still mucho goodness left and I then use it at night with a party bowl whip and a heat gun to blow massively cloudy bags that I have to use through water. Hey, works for me...
If it's a day with no appointments I might just use the bag system from the start. Find I can temp step four bags from 370/390/410 and finally 430. If I'm using ABV from the pucks I can still usually get 2 bags, one at 400 and another at 430. I can get clouds from any of my portables at will, just a matter of drawing more heat into the chamber with breath control. Sometimes I do that, but mostly I go for flavor.
