Both are somewhat fine if the relationship is short-term. You may choose someone you love to see if they can love you back. Or you may choose someone who loves you more than you love them and try to manage your feelings to reciprocate their feelings towards you. Another possible reason, if you choose the former, is to satisfy your desire to love regardless of you would emotionally get hurt in the process with a justification of more meaningful life than someone who chooses the latter, simply to take advantage of the circumstances.
It's a different story if your aim is long-term because one of you will surely end up miserable no matter what you choose. No one wants a miserable life at the very least and no one wants a partner in life who is miserable. We have no lacking of dramas and movies which had already demonstrated this idea, and for some reasons, we somehow end up feeling sorry for the character.
The best option is to love someone who can reciprocate your feelings. It is not only the right choice but it is also optimal in rasing a healthy family in the future and building a relationship. It is way way more meaningful that the option of either you are only the one getting or receiving love. It is no mystery why the idea of reciprocity is a golden rule. It is the key to long-term relationship.
