I'd rather be vaping on an e-cig than smoking a cigarette or a cigar. Hands down, no contest. Not just because of the money I'm saving, although that's great. It's the pure enjoyment of it. A new cartomizer, freshly filled with my favorite juice (it's KBV's "OMG!" at the moment) is definitely a treat.
E-cigs helped me quit a 4 year cigar habit, before that a 25 year cigarette habit. It's a great smoking substitute because you get that hit of nictotine, as with a nicotine patch or gum, and you also get the hand-to-mouth satisfaction. Great for taking a breath and a dramatic pause, like Humphrey Bogart with an analogue back in the old days. Here's hoping I can say "Here's lookin' at you kid..." to my wife for many more years than I would have if I kept on smoking instead of vaping.
