I have been to all Marriott Prop. in Bodrum and the Rixxos.
Hands down the Rixxos beats them all if you bringing your kids.

Le Meridien, OK beach, good food, soso rooms and villas
Edition, great service, good food, beach is ok but not crazy
Caresse dated rooms, food ok, beach ok, but boring

the Rixxos has renovated suites and rooms now, it offers an amazing kids club, paddle, nice beach and water sport acitivites, like waking and diving etc.
food was the better than most super exclusive high end resorts i have been to. i rate the food better than at the cheval blanc maledives here. its a buffet, but everything is fresh and they had an amazing selection.

if you have to choose accor vs marriott, rixxos with kids, and edition if you are adults only
