While I dont have a drill - I have a woods seeder. It allowed me to do more acres in the same amount if time. I used to spray, mow, disk, spread seed, and cover. I went over each plot five times. Now, depending upon the condition of the plot, I may spray, and/or mow, and plant. I save either two or three passes. A drill is not the cure all for everything. It is two wet to get it in the field right now, so I just sprayed and planted five acres of millet with my polaris ranger. I still use, every single year, a bag spreader, electric mount seeder on my ranger, a pto spreader on my tractor, and my woods seeder.
I would say all in all, time and labor aside, I think a sprayed, mowed, disked, seeded, and drug plot looks better. And I am including my woods seeder or a dedicated drill. The old fashioned way provides full, even coverage, even on more uneven ground. No planting rows seven inches apart. All filled in. Beauty is in the eye of the beholder
