Your question makes it sound like you're surprised that anyone would prefer stainless. And it makes me curious what your age is (I'm 50, I wouldn't ask if I weren't willing to tell). Early stainless steels weren't very good for knife blades, but they have improved significantly since the 60's, 70's, and 80's. So I wonder if your only experience with stainless steel blades is from those early days.
Personally, I prefer stainless. Low maintenance. I don't have to worry about humidity, or a little moisture on the blade or in the pivot area.
These days I hardly need a knife at all. But back when I was working, and my jobs were hot and sweaty, even stainless steel would sometimes rust a bit in my pocket, including my Bradley Alias with s30v stainless (the last "super steel" I purchased).
By the way Fass, you didn't mention which you prefer and why
