Hi Jay, It really depends on your data (size of if and if you need to do some extra handling e.g. sorting, data manipulation, data source level attribute filtering .. ).
So as a rule of thumb, very large data sets (>1gb) that require on-fly pre-processing (OpenStreetMap) or need to have read/write access are better served by PostgreSQL/PostGIS. Shapefiles + index are good for static things like boundaries. In my experience < 1Gb shape file s perform reasonably good.
