I agree that Cap was the worst. I thought Iron Man started the best, had the best artwork and I liked the way they used Hulk. Wasn't it also the quickest book to lose its initial creative team? I think all four books were covered by fill-in artists before they finished 12 issues. Maybe the least necessary contribution was the extra 13th issue of each where they Amalgamed Marvel with Wildstorm for some reason.
I think I liked Fantastic Four the best at the time because it was closest to how it was “supposed to be”. Iron Man’s origin got tied in with Hulk’s, and maybe Doc Samson’s?
I agree the Wildstorm stuff was weird and pointless.
