If you've got 6 in 1's and want them smoother just throw them in a blender until smooth. I use a immersion blender on ground or crushed tomatoes before pouring them out of the can. I usually use crushed tomatoes to make a puree rather than whole tomatoes because most seeds have already been removed. If I need to make a puree from whole San Marzanos then I'll deseed them first but that's a pretty lengthy process...but the tastiest.
