I have always done it like one really long mortise and tenon like MMWood. It just never occurred to me to use actual tenons and I never saw it done that way til recently. The Mortise and Tenon makes more sense though. The individual M&T's would seem be much stronger than one long groove so splitting is less likely - maybe.
