It depends on what your goals are. Because you want to clerk for a judge, law review is the better choice. However, you seem to already know that.
For most people, a lot of things are more interesting than journal work. (However, this may not be true in my case. I have yet to find out.) Most people don't join a law journal because it's interesting; they do it because it looks good on a resume and it's good experience. (Although arguably knowing whether to capitalize the "S" in "see also" following a previous citation is not an essential skill for a lawyer.)
What do you want to do after clerking for a judge? If BigLaw or academia, I would say go for law review. (However, if you graded onto law review, then you may have sufficient access to these career options anyway. Law review could just be the icing on the cake.)
