As they say, the grass is greener on the other side. I think that men yearned for immortality because they felt that mortality wasn't as good, but maybe some of the elves (secretly) yearned for mortality- to leave the world and its troubles and cares behind, and dwell forever with Eru. I do think that both gifts were equal if different. This is (in my opinion) one of those plans that we can never fully understand. One just has to trust in God and know that His will is for the best, even if we don't understand it.
