who did it better?

Michael Bolton and Mark Mangold (the keyboardist from Touch) wrote "I Found Someone" in 1985 for Laura Branigan. A few years later in 1987 Michael Bolton was working with Cher on her comeback album after a hiatus from recording to work on her film career, and they re-recorded the song. It ended up being a hit for Cher, and Laura Branigan ended up working with David Hasselhoff on a song for the Baywatch soundtrack and dying alone in bed at the age of 47. Later on in life, Michael Bolton recorded his own version. Mark Mangold did too but I can't find it anywhere. My question to you is...WHO DID IT BETTER?
