I am a dual EU citizen (which countries is irrelevant here, but both full EU members) and am wondering which of my two countries I should register to vote in for the next European Parliament Elections, in order to maximize the "value" of my vote.

Based on this answer I can only vote in a single country, but from this answer by the EU Commission:

the Commission considers that the possibility for EU voters with a dual nationality to choose where to vote should be encouraged.

My question comes from the observation that one person's vote doesn't exactly count as one in a variety of elections.

I assume variables to consider probably include ratio of elected parliament members to population (as the EU Parliament seats are allocated according to degressive proportionality), but there are probably other elements to take into account.

How should I approach this question, and what information should I take into account?

    You may first want to double check that the other (or both) your nationalities allow non-resident voting. That isn't guaranteed across all the EU member states.

  • I think, that without knowing your views and both nationalities, this can not be answered. There's too many variables. However, with that data included, it might becomes too narrow a question for politics SE.

You gain nothing if you vote where your vote counts most, and the candidate you vote for doesn't get elected. Probably.

  • Is the predicted outcome in one of your countries particularly close? Your vote might help to make the difference.
  • Are there "first past the fencepost" or "threshold" voting systems that would make your vote likely to be irrelevant?
  • Do you feel a special affinity towards any one party or candidate, and do you want her or him to be elected?
  • Do you dislike any one party or candidate, and would you use your vote 'tactically' to keep that candidate out?
