Riverside is not more peaceful - it is the louder and more children-filled of the two. I stay only at FQ these days - the convenience of the busses stopping at FQ first can't be overstated. It depends on what you are looking for -- Riverside has a sit-down restaurant - FQ does not. FQ has a better larger pool, but Riverside has a nice pool on the island, and several small "quiet pools" (NOTE: Quiet at WDW is a bit of a misnomer as I have always found the resorts to be noisy to some degree). I have always found FQ to be the quietest of the mid-range resorts, but it is better for adults without children. There are arcades at both, but the family amenities at Riverside far surpass those at FQ. Both resorts share a boat system to Downtown Disney. You can't really go wrong with either resort. And for those who have sayed there before, there are an equal number of lizards at either one, the ones at FQ just have southern drawls.
