What, if any, is the advantage of a speed density patch over just failing the MAF on a GM Gen 3 DBW LS running Naturally Aspirated.

It's not such a big deal on the Gen3 since this ECM has a conventional VE table. It's more useful with the later ECMs that utilise VVE as there are limits with the algorithm on exactly how granular you can get with the VE numbers.
