Yeh love comes with no resell rights , on the other hand, you are free to spend, invest or do blah blah with money
If I was asked this question 10 yrs ago, I would have said LOVE... but now, MONEY conquers the world!
I would go for the billions, because then the girls would come for me anyway with all that money . Even so, a relationship is not everything in the world, with all that money you can do a whole lot more with your life, which does not involve having a relationship.
I would like to go for Love. If you are having your Love with you, you can win the world. Nothing is important than Love,
