The augers today have come a long way. My advice when it comes to augers is stick with the 2 HP. I have had both Jiffy and Strikemaster. I now only use Strikemaster. I believe they make a better product by comparison. Both will do the job, I just prefer Strikemaster.
If you are looking for a great all around auger, you can not go wrong with a 8″ Lazer Mag. I have several, but one of my favorites is my little 7″. Man does that thing fly!!
