16mm, 20mm, and 23mm are rarely ever used. I've never used a 27 or 32mm before. 30mm is used on ford cars axle nuts. I have a 34mm and 36mm for axle nuts.
That set should work out just fine for at home use, you will need a 34/36mm for axle nuts though. I currently have a cheap harbor freight set and half of them are broken. And it didn't include a few sizes I want. I hate them, but they were free to me. Call me crazy but I'm buying another full snap-on set for home use as well. Used, of course.
For work though, My impact sockets do not skip a single size from 10-24mm. Thank god for that, because there's always that one day you'll need it and never get over it if you bought a cheap set.
Don't buy shallow impact sockets, I've never needed them. Swivel impact sockets are much more important if you want to buy more.
