Well, yeah, I was meaning romantic love though
Although familial love is also biologically based.
I'd say the best kind of love is the kind shared between friends. That's the only love that doesn't have some explicitly creepy driving force behind it, and isn't restricted by things like gender, attractiveness, etc. I've always thought having a great close friend is always better than having a romantic relationship that's going to eventually end anyway. And if you happen to form a very close friendship with someone that lasts, and also leads to something else that's just as grounded as solid, that's the absolute best you can get
