Love is defiantly more important. I understand where your coming from...without lust there will be no love immediately. However, if you developed love for that particular person due to their personality and characteristics then it is certain there will be lust and they will appear beautiful to you in your eyes. Hence love wins and lastly 'lust' will disappear if you 'liked' them because of their looks.
