It's decision time for the Bachelorette and honestly, Ali Fedotowsky has her work cut out for her. "She really can't go wrong," says host Chris Harrison of the man-tastic task facing this season's singleton. So will it be Roberto, the hard-bodied insurance agent from Charleston, South Carolina, or sexy and sensitive Massachusetts landscaper Chris L.? Here's Harrison's take on Ali's prospective picks.

Roberto: "Her relationship with Roberto has been amazing from the beginning," says Harrison. "When he got out of the limo, she almost fainted. But that was looks. It took a while for their relationship to get to the point of 'Is it real?' Now they have not only the chemistry, but they have that kind of relationship, too."

Chris L.: "When they went to [his] hometown, you saw Ali and Chris go from good friends who are compatible to that chemistry she had with Roberto from Day 1," says Harrison. "We heard stories of how his dad treated his late mom, and you know that's how Chris is going to treat his wife. For a woman, that is a big deal. He's one of the greatest guys I have met on this show."

The Bachelorette airs tonight at 8/7c on ABC
