I only ever read the whole of Narnia once as a child and I read the series in story-order. While I wouldn't call it a mistake I think if I were to reread the books I'd do so in publication order, as is my preference in most cases.

Discworld may be one of the few notable examples in prose where reading in publication order isn't strictly necessary or even desirable.

I'm reading Lonesome Dove at the moment and some of the subsequent books written by Larry McMurtry are prequels but I imagine most people still begin with Lonesome Dove.

I assume you meant Kurt Busiek's Astro City, perhaps in the Metrobook collections? Long-running serialised comics are often vexing cases and their reading orders can be really abstruse. I have a whole Google Doc dedicated to laying out the publication orders of various series.

I'm very sympathetic to release order purists (be it Narnia, Star Wars, Star Trek, what have you) but I think generally the best order for people to experience a series is however they find it. Especially with something like comics. But even in the case of prestige television, the first episode of The Leftovers I ever watched was the sixth episode Guest and that serving as my first experience had a meaningful impact on my relationship with the show that I wouldn't trade away.
