Love for sure for me, it's far harder to acquire than money.
I will always have enough money for basic monetary needs but I can't say the same for love. I'm in the position though of where I always have enough money but I didn't get love growing up from family, so maybe the most important thing is what we lack? I can't imagine how I'd feel if I had got love from family, it's a totally alien concept to me and I have no clue how I'd feel then. If I had a partner (that won't ctb), then I'd still say love because it would be what I had with them and still the most important thing to me, but having love also means making money is more important since its no longer something I'd view as just what I needed for basic living, I need money for partner too then. I love people that I'd consider my kids but it's not the same.
Certainly having zero money would be depressing and I'd feel 100x worse then. If that happened to me where I didn't have enough money to live on I might feel different but it's not plausible right now.
