I'm sure I read/heard somewhere that Riker was a character the writers had trouble with finding what to do with. Having him stick around for fifteen years as XO makes no sense, especially for an up-and-coming officer Riker was supposed to be. Having him reassigned would've made sense, leaving the door wide open for him to return on guest appearances and getting to see his crew as well.
Had he taken the Aries it's most likely Data would've become the new Numbah One, which would leave a key role open and meant they'd need a new character (a strong female officer could've been added to help balance out the roster). Or if he'd taken the Melborne then Shelby could've been added to the cast, giving a new look to the command team of the ship.
