As long as you are willing to always restrict hot water use to one fixture, and it can meet your needs, a tankless may satisfy you. If you were regularly trying to fill a tub, or use hot water on occasion for clothes, or tried to use them while you wanted to shower, you'd be much less satisfied. It also depends on your utility rates - where I live, it can approach $0.20/KwHr delivered...NG is MUCH more economical to heat water, cheaper to install and service.
