I would say love marriage. How can you marry someone for your whole life unless u know her.
Arranged marriages are good cos your parents know the best for you. After all, mom is the best in the world however they can't always be right. If arranged marriages were always good then we wouldn't be seeing all those after marriage cases where the husbands exploits wife.
Love Marriage is the way to go, or if you are going for arranged marriage then few months before the marriage let the couple interact with each other, let them meet, talk, understand each other.
