I would think that it is more economical and environmentally better to use an oil burner, condensing would be even better. A modern boiler would be a lot more efficeint than an open fire. A stove may be a different matter. I really think you can't take out the hassle factor because it really is a hassleI.E lots of cleaning, no option for automatic start etc.
Your best bet would be to have both so they can compliment each other.
