My perspective is the Suspense #4 is probably more scarce than the #3. You don't see a #5 often either.
For Chesler, the Punch #12 is not seen often, but maybe less than 30 copies out there? The Dynamic #8 is rarely seen, so maybe less than 20 of those out there. The Scoop #2 is also not seen to oftern, I would say less than 20 copies of that book as well.
Truly scarce in my opinion is Wonder Comics #1 and #2, the issues preceding Wonderworld. Wow What a Magazine, all issues are less than 10 copies I feel.
These are all off-beat titles that I have coveted since I began collecting in the 80s', so I am gauging my scores based on my experience.
I came back t ammend this post. Another book that I did not know existed until last year was a authentic Blazing Comics #5. You see these things all the time, there are tons of them out there, but almost everyone is some remainder book with the #5 cover. What I am talking about is a true #5 book that contains the last Green Turtle story. Jeez I am such a dork for knowing such things.
