Good advice.
I don't think it will affect your fuel economy much, if at all. Why not stick with the size originally specified for the vehicle? At least that way your speedometer and odometer will read correctly.
Personally, what I look for in a tire is the best wet traction available and good tread wear. On dry pavement even bald tires will work. On wet pavement it's a whole 'nother ball game, as it may save you from being involved in a crash. To me having the optimal advantage in bad weather is worth more than the few cents saved in fuel.
