Same brand for the entire 39 years I smoked: Old Gold filter kings, "full flavor".
I was consuming from a pack and a half to two packs a day when, after trying e-cigs a second time, I flat quit smoking. Well that would be "flat quit' once I'd run out of the two packs of real/analogs I already had on hand (as I remember, by interspersing them with vaping, I managed to stretch those last forty smokes out for about a week!).
I don't know how common my experience is, but when I tried vaping that second time, the first time being just prior to the FDA's abortive ban (some absolute rubbish that I'd I picked up at an area tobacconist,) I had no thought whatsoever of quitting. Rather, I purchased the product partially for whatever novelty/conversation value it might provide at my job, and partly in the hope that, by acting as a sort of stop-gap or diversion, its use might help me cut down on my ridiculously frequent trips to the outdoor smoke-shack at work.
