Ask any one, your professors, your instructor(s) or advicer(s), your dean(s), any one who qualifies as an economist, dude, and be adviced by the common sense, which you really need to learn.
No one would trade a JF/JFE with a RFS, unless he or she was hopelessly stupid or totally insane. JF is as good as JFE. Some might slightly prefer the former; others might prefer the latter. And both of them are top journals in both Econ&Finance fields.
Some finance guys might even believe JF/JFE is as good as TOP4. I would say that they are not crazy or exaggerating within the field of finance (or financial economics).
