I don't know. I think you have to find the process that works best for you. I do the exact opposite of a sparse plot point first draft. I write long repetitive meandering first drafts that still need a ton of work, but it's usually cutting a lot of unnecessary stuff rather than adding details. But I get excited about trying to convey everything I'm thinking for my characters or scenes and so I try to get it all down. I wouldn't enjoy things as much if I just had to go through and write only the major plot points.
