Done it both ways. Hated my dinette in one of my Tiffins' as it had no room between the table and the seat. First we had a narrower custom table built. Finally changed in to free standing but kept the booth so I could install if next owner desired it. Just bought a 29DS Class A Mirada and it has a booth dinette. We are keeping this one as the room between seating and the table is awesome.
My only complaint is that you can't see the mid-ships TV from one side. Looking into a strategic mirror location.
