Quantified Impressions, a communications analytics company, set out to find out the best phrase for love on Valentine's Day.
The Austin, Texas, based company asked 100 people to rank their favorites from the 20 most popular ways to say "I love you."
Fifty men and 50 women also ranked their least favorite.
Men and women differed on their favorite Valentine's Day phrase. Men's top choice was "You are the love of my life!" while women preferred "You're my soul mate and the love of my life."
Both sexes agreed that "I think that I love you" is the worst way to express your love.
Noah Zandan, the president of the company, recommends keeping your Valentine's Day expressions personal and simple.
"I'd want to make sure that I don't over explain what I'm saying," Zandan told ABC News.
He added that it's best to be direct but not to have to provide reasoning behind what you're saying since originality always helps.
