As a married person, I would say it doesn't matter. Love marriage definitely sounds good because it is a slow process. You get to know each other better before making THE decision. Arrange is like an express lane. You skip all these processes or at least out source them to others to verify. One thing about arrange is that you will have lot of moments of surprises, which is good. I married my wife after we had been girl friend and boy friend for 7 yrs. By the time we were married, we knew everything about each other, which I thought was boring until our daughter born. But I am happy that I got the best woman for me. So there is no definite path to marriage. Either of them can be good or ugly. One thing for sure, your freedom will vanish in the air. Here one helpful mantra.
1. If you can find yourself a wife, go for it.
2. If not, don't waste your time trying. Let your family or friends do it for you. Remember you will only grow old.
Good luck,
