I've had all the variants listed above in my collection for years and they are only now showing up as unrecognised items.
From a collector's point of view, the kind of paper a comic is printed on makes a difference to me. I would would much rather have the glossy paper than newsprint as the glossy paper ages much better. I know that if I bought a comic off of Atomic Avenue with the expectation that it was printed on glossy paper and instead received one printed on newsprint, I would not be happy.
And for what it's worth, I bought all the newsstand editions from mycomicshop.com, and they listed the newsstand and direct editions separately.
