If given the choice, I'll use a stub/italic all the time. Having said that, for most daily writing and correspondence, I rarely go over the common 1.1mm width, and only use the wider ones that I have for greeting cards, special notes, or addresses. I sometimes feel that if I pick up a standard M or F non-italic nib, especially after writing with italics, it is almost like the color has gone out of the world. I just lose expressivity.
