Depends on what you want to do: Raster/vector analysis in vector space (with ST_Intersection(geometry, raster)): smaller is better
Raster/vector analysis in raster space (with ST_Clip or ST_Intersection(raster, raster)): tile approximately the size of polygons is better No analysis: depends on your application.
