Davis Lynch is the Donny Douglas (Frasier) of Wings
They have a few similarities: Davis came in halfway through Wings and Helen Chapel became his fiancee. Helen broke off the engagement to start a relationship with Joe Hackett, Helen and Joe were married for a few seasons. Donny came in halfway through Frasier and Daphne Moon became his fiancee. She left him at the altar to start a relationship with Niles Crane, Niles and Daphne were married for a few seasons.
I would say yes. Donny was a more likable character, Saul Rubinek was also a better actor than Mark Herelik. But Niles had been pining for Daphne from the start of the show and fans wanted them together.
